Answer:
Step-by-step explanation:
A parabola has the following format:
If a is positive, it's minium value is:
In which
Factoring:
, in which are the intercepts.
In this question:
So
Suppose a = 1, we have:
The minimum value will be:
We want this minimum value to be -4, which is 4 times the current minimum value, so we need to multiply a by 4. Then
And the parabola 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 =
