How do I Solve for f of X

The video tutorial guides students through solving a math problem involving two functions, F(x) and G(x). The instructor breaks down the problem into manageable steps, first calculating G(6) and then F(-5). The video emphasizes the importance of using parentheses when dealing with negative numbers in calculations. Finally, the instructor simplifies the expression G(6)/F(-5) to arrive at the solution, 1/2, while encouraging students to practice and understand each step.

What is the expression for G(x) as given in the problem?

• G(x) = x^2 + 2x - 4

• G(x) = 4x^2 - 5x - 5

• G(x) = 2^x - 4

• G(x) = 3x - 5
