1-52.
  1. Given f(x) = 2x + 5, g(x) = x2 − 1, and h(x) = square root of x plus 2, find: Homework Help ✎

    1. f(g(−2))

    2. g(f(h(2)))

    3. f −1(x)

    4. f(g(h(x)))

Evaluate g(−2) first. Then substitute that value in the f function.

1. Switch the x and y's
2. Solve for y.

Follow a similar process as shown in part (b).
