Math Problem Statement

g(x)=1/2 f(x)-2 -> g(x)=1/2(x)^3-2

Solution

The given transformation starts with the function:

g(x)=12f(x)2g(x) = \frac{1}{2} f(x) - 2

and results in the following form:

g(x)=12x32g(x) = \frac{1}{2}x^3 - 2

This means that the function f(x)f(x) must be f(x)=x3f(x) = x^3, since the transformation implies that f(x)f(x) has been replaced with x3x^3 in the final equation.

Explanation:

  1. The original form is g(x)=12f(x)2g(x) = \frac{1}{2} f(x) - 2.
  2. To match the final form, you substitute f(x)=x3f(x) = x^3.
  3. After substitution, the equation becomes g(x)=12x32g(x) = \frac{1}{2} x^3 - 2, which matches the given final form.
