4. The graph of h(x) = x^2 was transformed to create the graph of k(x) = -4x^2? Which of these describes the transformation from the graph of h to the graph of k? A.) A reflection over the x-axis and a vertical
stretch
B.) A reflection over the x-axis and a vertical
compression
C.) A reflection over the y-axis and a vertical
compression
D.) A reflection over the y-axis and a vertical stretch

A. A reflection over the x-axis and a vertical stretch.

Step-by-step explanation:

Let , to obtain , we need to use the following two operations:

(i) Vertical stretch

,

(ii) Reflection over the x-axis

Let prove both transformations in :

Step 1 - Vertical stretch ()

Step 2 - Reflection over the x-axis

Hence, correct answer is A.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
