Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros.
g(x) = x3 − x2 − 4x + 4
g(x) = x3 + 2x2 − 9x − 18
g(x) = x3 − 3x2 − 4x + 12
g(x) = x3 + 2x2 − 25x − 50
g(x) = 2x3 + 14x2 − 2x − 14

For the graph of the function g(x) = x³-x²-4x+4, g(1.535) = -0.879 is the minimum point and g(-0.869) = 6.065 is the maximum point. g(1/3) = 2.593 is the inflection point.
What is a graph of a function?
The graph of a function f is the set of all points in the plane of the form (x, f(x)).
To graph the function ⇒ substitute with the values of x and get g(x) but at first we need to find the critical points (maximum, minimum, inflection) which can be found by differentiating g(x) with respect to x.
What is an inflection point?Inflection points are points where the function changes concavity, i.e. from being "concave up" to being "concave down" or vice versa.
What are maximum and minimum points?Points in the domain of definition of a real-valued function at which it takes its greatest and smallest values; such points are also called absolute maximum and absolute minimum points.
g'(x) = 3x² -2x-4 = 0
⇒ x = 1.535 and -0.869
⇒ maximum and minimum points
g(1.535) = -0.879 which is the minimum point
g(-0.869) = 6.065 which is the maximum point
g"(x) = 6x -2 = 0
⇒ x = 1/3
⇒ point of Inflection: g(1/3) = 2.593

Give an example of an infinite geometric series having no sum.
Answer:
An example of an infinite geometric series having no sum is a1 + a1r + a1r2 + a1r3 + a1r4 and so on. 8+12+18+27+... if it exists. Since r=32 is not less than one, the series does not converge. That is, it has no sum.

1, -1, 1, -1, 1, -1, ... is an example of an infinite geometric series having no sum.
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
An infinite geometric series is a sequence of numbers in which each successive term is generated by multiplying the previous term by a constant, known as the common ratio.
An example of an infinite geometric series with no sum is a geometric series with a common ratio of -1, such as the series 1, -1, 1, -1, 1, -1, ...
This series oscillates between 1 and -1 forever, and so its sum is undefined.
The common ratio is -1.
This means that for each term in the series, the value is multiplied by -1. As a result, the series oscillates between 1 and -1 forever, which means that the sum of the series is undefined.
Hence, 1, -1, 1, -1, 1, -1, ... is an example of an infinite geometric series having no sum.

Find the value of x.
I need help please!
Answer:
24
Step-by-step explanation:
Keep in mind that exterior angles are mentioned. So let's find the interior ones. Note that the interior and exterior angles are forming straight lines. So something plus 84 equals 180 degrees.
180-84=96
180-120=60
The sum of three angles of a triangle is 180 degrees. X is an angle. So we can form an equation to represent this. Then just solve for x!
96+60+x=180
156+x=180
x=24
John's garden is 12ft long and 15ft wide. How
long is John's garden in yards?
Answer:
4 yards long
Step-by-step explanation:
John's garden is 12 ft long and 3 ft go into a yard. With this information you then divide 12 by 3 to see how many yards would go into the 12. 12/3=4
Answer:
4
Step-by-step explanation:
3ft = 1yd
They only want to know how long in yards not the rest so
12ft = ?yds
So set up the problem.
12/3 = x/1
Solve
1(12) = 12
12 divided by 3 = 4

u have $9.60 to buy avocados for a guacamole recipe.Avocados cost $2.40 each.
Identify an inequality that represents the number x of avocados you can buy.
Answer:
23.04
Step-by-step explanation:
Multiply 9.50 and 2.40 and the put the decimal between the 3 and the 0 :)
The inequality that represents the number x of avocados you can buy will be 2.40x ≤ 9.60.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
U have $9.60 to buy avocados for a guacamole recipe. Avocados cost $2.40 each.
Let 'x' be the number of avocados. Then the inequality is given as,
2.40x ≤ 9.60
Simplify the equation, then the value of the variable 'x' is given as,
2.40x ≤ 9.60
x ≤ 9.60 / 2.40
x ≤ 4
The inequality that represents the number x of avocados you can buy will be 2.40x ≤ 9.60.

The completed construction of a regular hexagon is shown below. Explain why AACF is a
30°-60°-90° triangle. Show a picture, please!
Answer:
You can prove that angle C is 30°. This is because we know that angle B is 120° also, and interior angles add to 180°, which makes angle BCF 60°. Then we can divide this by 2 as angle BCF is bisected by AC, so, therefore, angle ACF is 30° as 60 ÷ 2 = 30.
You can then prove angle A is 90°. First, we can find angle BAC because it is part of a triangle, and angles in a triangle add to 180°. This means we can do 30 + 120 = 150, and 180 - 150 = 30° which is angle BAC. Then we do 120 - 30 = 90, as the whole of angle BAF is 120°.
