1-41.
  1. Given f(x) = x2 + 2x and g(x) =square root of x plus 1, find the following: Homework Help ✎

    1. g(x − 2)

    2. f(g(8))

    3. g(f(8))

    4. f(f(1))

    5. f(x + 1)

    6. g(f(x))

Replace every x in the g function with the expression (x − 2). Then simplify.

Find g(8) first. Then replace every x in the f function with the value of g(8). Simplify.

Find f(8) first. Then replace every x in the g function with the value of f(8). Simplify.

Find f(1) first. Then replace every x in the f function with the value of f(1). Simplify.
