1-130.
  1. Let f(x) = x2 and. Evaluate the following expressions. Homework Help ✎

    1. f(3)

    2. f(−3)

    3. g(9)

    4. g(f(3))

    5. g(f(6))

    6. g(f(x))

f(3) = 9

Since f(x) and g(x) are inverse functions for x ≥ 0, g(9) = f(3) =______________

Recall that f(x) and g(x) are inverse functions for x ≥ 0, and the definition of an inverse function: f(g(x)) = x.

Because f(x) is even, f(−3) = f(3) = part a = _____

Plug in your answer from part (a).

Refer to the hint in part (e).
