Which parent functions have a locator/vertex point of (0,0)
Answer:
Graphing quadratic functions The shortcut to graphing the function f(x) = x2 is to start at the point (0, 0) (the origin) and mark the point, called the vertex. Note that the point (0, 0) is the vertex of the parent function only.

Which graph represents y as a function of x?
Answer:
The third picture (shown below as an attachment)
Step-by-step explanation:
This problem wants us to detect which one is a function. The definition of a function is that for every x-value you input into the function, you will get ONLY ONE y-value output. A way to check this when it’s graphed is to scan left to right (vice versa) and if there are two lines that meet at the same x-values, then it’s not a function. We can eliminate the circle graph because there are two lines that meet the x-coordinates. Like how when x is -5, the y-coordinate is both 7 and -7. This proves that for the x-coordinate -5, the y-coordinate has two y-coordinates, 7 and -7. Therefore, the circle graph is not a function. Same thing for the absolute value graph (the v-shape graph). There are two lines that overlap on the x-values. The last graph (the straight vertical line) is definitely not a function because all y-values are equal to the x-value 3, which means that multiple y-values share an x-coordinate. The third option (the correct one) is a function because there are no overlapping lines. You might say that when x is 1, there are two y-coordinates, 4 and -4. But the higher line has an open circle at 4 which means that the line doesn’t include 4. So they don’t overlap, which makes it a function. Choose the graph of option three (the attached picture).
I hope you understand.
Hope this helps and answers your question :)
The third graph represents y as a function of x.
What is a function?A relation is a function if it has only One y-value for each x-value.
The definition of a function is that for every x-value you input into the function, you will get only one y-value output.
A way to check this when it’s graphed is to scan left to right (vice versa) and if there are two lines that meet at the same x-values, then it’s not a function.
We can eliminate the circle graph because there are two lines that meet the x-coordinates.
For second graph there are two lines that overlap on the x-values.
The last graph (the straight vertical line) is definitely not a function because all y-values are equal to the x-value 3, which means that multiple y-values share an x-coordinate.
The third option (the correct one) is a function for each value of y there is one x value.
Hence, the third graph represents y as a function of x.

Use the Distributive Property to solve the equation. 3x-5(x-4)=-9+5x+15
Answer:
I keep getting no solution
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(x−4)=−9+5x+15
(5)(x)+(5)(−4)=−9+5x+15(Distribute)
5x+−20=−9+5x+15
5x−20=(5x)+(−9+15)(Combine Like Terms)
5x−20=5x+6
5x−20=5x+6
Step 2: Subtract 5x from both sides.
5x−20−5x=5x+6−5x
−20=6
Step 3: Add 20 to both sides.
−20+20=6+20
0=26

Write out the form of the partial fraction decomposition of the function (as in this example). A) x4 − 2x3 + x2 + 2x − 1/x2 − 2x + 1B) x2 - 1/x3 + x2 + x
Answer:
A. [tex]\mathbf{\dfrac{x^4-2x^3+x^2+2x-1}{x^2-2x+1 }= x^2 + \dfrac{A}{x-1}+ \dfrac{B}{(x-1)^2}}[/tex]
B. [tex]\mathbf{\dfrac{x^2-1}{x(x^2+x+1)} = \dfrac{A}{x}+ \dfrac{Bx+C}{x^2 +x+1}}[/tex]
Step-by-step explanation:
A.
Given that:
[tex]\dfrac{x^4 -2x^3 +x^2+2x -1}{x^3 -2x +1}[/tex]
[tex]\dfrac{x^4 -2x^3 +x^2+2x -1}{x^3 -2x +1} =\dfrac{(x^4 -2x^3+x^2) +(2x-1)}{x^3 -2x +1}[/tex]
[tex]=\dfrac{(x^4 -2x^3+x^2)}{x^3 -2x +1} + \dfrac{(2x-1)}{x^3 -2x +1}[/tex]
[tex]= \dfrac{x^2(x^2-2x+1)}{x^2-2x+1}+ \dfrac{2x-1}{(x-1)^2}[/tex]
[tex]\dfrac{x^4-2x^3+x^2+2x-1}{x^2-2x+1 }= x^2 + \dfrac{2x-1}{(x-1)^2}---(1)[/tex]
Further, the partial fraction decomposition of [tex]\dfrac{2x-1}{(x-1)^2}[/tex] can be written as:
[tex]\dfrac{2x-1}{(x-1)^2} = \dfrac{A}{x-1}+ \dfrac{B}{(x-1)^2}[/tex]
From equation one, replacing the values; we have the partial fraction decomposition of the function to be:
[tex]\mathbf{\dfrac{x^4-2x^3+x^2+2x-1}{x^2-2x+1 }= x^2 + \dfrac{A}{x-1}+ \dfrac{B}{(x-1)^2}}[/tex]
B.
Given that:
[tex]\dfrac{x^2-1}{x^3+x^2+x}[/tex]
[tex]\dfrac{x^2-1}{x^3+x^2+x} = \dfrac{x^2-1}{x(x^2+x+1)}[/tex]
Therefore, the partial fraction of decomposition is:
[tex]\mathbf{\dfrac{x^2-1}{x(x^2+x+1)} = \dfrac{A}{x}+ \dfrac{Bx+C}{x^2 +x+1}}[/tex]
