Answer:
g(x) = -8x^3 +9
Step-by-step explanation:
The form ...
-f(ax) +b
represents the function f(x) reflected over the x-axis (-f(x)), compressed horizontally by a factor of "a" (f(ax)), and translated up by "b" units (f(x)+b).
Your sequence of transformations results in ...
g(x) = -f(2x) +9 = -(2x)^3 +9
g(x) = -8x^3 +9
