please and thank you

How is the graph of g(x)= -(2x)^3 related to the graph pf f(x) = x^3

answer: I don't understand the answer..thank you

the graph of g(x) is a horizontal compression of the graph of f(x) by a factor of 1/2 and a reflection across the x axis.

Well you can right away see that g(x) opens downwards while f(x) opens upwards.

Perhaps you need to plot both graphs...
This will help you see what the rules are telling you about the compression factor...
