Can someone help me answer this?

f(x)=4x^2= horizontal compression by factor of 4

f(x)=x^2-4= vertical translation down 4 units

f(x)=4x^2= vertical compression by factor of 4

f(x)=(x-4)^2= horizontal shift to right 4 units

Step-by-step explanation:

hope it helped

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
