Answer:
Step-by-step explanation:
Based on the two graphs I see at the bottom of the photo, you're looking at a quadratic function. The answer you put in is a linear equation.
Quadratic functions follow the form , where a, b, and c can be either positive or negative constants.
The table says that the equation, when graphed, should start at the top, slide to the bottom, and then slide back up to the top. So a must be positive.
c has to be -8 since it's the y-intercept.
So far, our equation is . We'll need to plug in some points in order to work out what and are.
Let's use as the first set of points, and as the second set.
Now we have 2 equations with 2 unknowns. Solve for one variable:
Now substitute that into the second equation:
Now substitute the result into the first equation.
Now substitute our values back into the original equation:
Please let me know if this is correct.

Step-by-step explanation:
On a unit circle, the only points where y = have an x coordinate of or . Since only one of those is an option, the answer is .
<u>Answer:</u>
D of Y = (-3/2, -1)
<u>Step-by-step explanation:</u>
We are given three points on the graph:
X (4, 0)
Y (3, 2)
Z (2, 2)
and the scale factor of dilation which is .
Given that, we are to find the coordinates of Y after dilation. To find that, we will multiply the coordinates of the point Y with the scale factor.
Y = × , (-\frac{1}{2}[/tex] ×
Y =
The Exact Form : 1/2
Decimal Form : 0.5
