Let g(x) = (3x − l)². Homework Help ✎
1. Find g(−5).
2. Find g(a + 1) and simplify.
3. If g(x) = 49, find x.
4. Find g⁻¹ (x).

Answer (a):

g(−5) = 256

Hint (c):

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

Hint (b):

Substitute (a + 1) for x. Simplify.

Steps (d):

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