based on the graph, which statement about the function is true

a) the domain is the set of all real numbers

b) the domain is the set of all real numbers less than 3

c) the range is the set of all real numbers greater than or equal to 0

d) the range is the set of all real numbers greater than or equal to -9

An Exponential Function Is Graphed On The Gridbased On The Graph, Which Statement About The Function

Answers

Answer 1

Answer:

a) the domain is the set of all real numbers

Step-by-step explanation:

Given:

An exponential function and its graph.

A line parallel to [tex]x[/tex] axis is drawn at [tex]y=-9[/tex] which is a dashed line.

Dashed line means, the function does not attain a value equal to [tex]y=-9[/tex].

Domain of a function, [tex]y=f(x)[/tex] is the set of values which can be possible for the variable [tex]x[/tex] that can be given as input.

Range of a function, [tex]y=f(x)[/tex] is the set of possible values of [tex]y[/tex] i.e. the output of the function.

As seen from the graph, the domain of the exponential function does not have any constraint on it.

Therefore, any real number can be given as input.

So, a) The domain is the set of all real numbers.

Let us discuss about the range of function.

As stated above as well, the range of the function can not contain the value [tex]y=-9[/tex].

And there is no value possible below it.

So, the range is all real numbers greater than -9.

The answer is:

"a) the domain is the set of all real numbers"  is true.

Answers

Answer:

7 + 5i

Step-by-step explanation:

What is the square root of 25? Start by thinking about that.

Well, it's 5.

But because the 25 isn't positive, it's negative.

The square is 5i.

Then, you get 7 + 5i.

That can't be simplified any more, so that's your final equation.

WHAT IS X

Answers

Answer:

x=-7

Step-by-step explanation:

add 2x to -x to get 1=x+8, then subtract 8 to get x=-7

Answer:

x = -7

Step-by-step explanation:

1 Regroup terms.

-2x+1=8-x−2x+1=8−x

2 Add 2x2x to both sides.

1=8-x+2x1=8−x+2x

3 Simplify  8-x+2x8−x+2x  to  8+x8+x.

1=8+x1=8+x

4 Subtract 88 from both sides.

1-8=x1−8=x

5 Simplify  1-81−8  to  -7−7.

-7=x−7=x

6 Switch sides.

-7 = x

x=−7

Step 2:

Reduce the tail of the answer above to two numbers after the decimal point:

7.74

Step 3:

Round 7.74 so you only have one digit after the decimal point to get the answer:

7.7

To check that the answer is correct, use your calculator to confirm that 7.72 is about 60.

what is the factored form of x^3 + 125?​

Answers

Answer:

(X+5)(x^2-5x+25)

Step-by-step explanation:

Choose an equation that would be used to solve
0 = -x2 + 10X-8
(x + 25)2 = -8
O(x - 5)2 = 17
(x - 10)2 = 25

Answers

Answer:

(x - 5)² = 17

Step-by-step explanation:

Given

0 = - x² + 10x - 8 ( multiply through by - 1 to clear the leading negative )

x² - 10x + 8 = 0 ( subtract 8 from both sides )

x² - 10x = - 8

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 5)x + 25 = - 8 + 25

(x - 5)² = 17

Answer:

x=-1, x=3

Step-by-step explanation:

to solve by factoring:

1. swap the sides:  

0=(x-1)^2-4

2. expand the expression:  

(x-1)^2-4=0

3. rewrite and calculate:

x^2-2x+1-4=0

4. factor

x^2+x-3x-3=0

5. Factor... again

x(x+1)-3(x+1)=0

6. separate

(x+1) (x-3)=0

7. solve

x+1=0, x-3=0

8. and you end up with 2 solutions
