1-73.
  1. Given f(x) = x2 + x and g(x) = x + 1, find: Homework Help ✎

    1. g(f(x))

    2. f(g(x))

    3. For what value(s) of x will f(g(x)) = 2?

Substitute (x2 + x) for every x in the g function.

Substitute (x + 1) for every x in the f function.

x2 + 3x +2 = 2

Now set the equation equal to 0 and solve.
