Math Problem Statement

Given the function g(x) = 2 - 5x, find g(3x - 3).

Solution

The problem asks you to evaluate g(3x3)g(3x - 3), given the function g(x)=25xg(x) = 2 - 5x.

Step-by-step solution:

  1. Start with the function definition: g(x)=25xg(x) = 2 - 5x

  2. Substitute 3x33x - 3 for xx in the function: g(3x3)=25(3x3)g(3x - 3) = 2 - 5(3x - 3)

  3. Distribute the -5: g(3x3)=2(15x15)g(3x - 3) = 2 - (15x - 15) g(3x3)=215x+15g(3x - 3) = 2 - 15x + 15

  4. Simplify the expression: g(3x3)=1715xg(3x - 3) = 17 - 15x

So, g(3x3)=1715xg(3x - 3) = 17 - 15x, which matches the option 15x+17-15x + 17.

Answer:

The correct option is: 15x+17\boxed{-15x + 17}
