Question

Which transformations of ƒ(x) = 3x does h(x) = -3x - 7 represent?

A. reflection over the y-axis and shifted 7 units down
B. reflection over the x-axis and shifted 7 units down
C. reflection over the y-axis and shifted 7 units up
D. reflection over the x-axis and dilation by a factor of 3

Answer 1

Shifted down 7 unites, vertical stretch, reflected about the y-axis.

Explanation:

Answer 2

A.

Explanation:

from f(x)=3x to g(x) = -3x there is a reflection over the y-axis and then from the g(x)=-3x to h(x)= -3x-7 there is a traslation 7 units down. So, the correct option is A.
