Let g(x) = (3x – 1)2. Homework Help ✎

  1. What is g(–5)?

    g(−5) = 256

  2. Write an expression for g(a + 1) and simplify.

    Substitute (a + 1) for x. Simplify.

  3. If g(x) = 49, what are the possible values of x?

    Set (3x - 1)² equal to 49 and solve for x.

  4. Write an equation for g–1(x).

    Let g(x) = y. Solve for x. Then switch the x and y.

    Remember the ±.
