Question

Functions f(x) and g(x) are defined below.

Determine where f(x) = g(x) by graphing.
A.
x = -1
B.
x = 4
C.
x = -4
D.
x = -2

Answer 1

C. x = -4

Explanation:

Graphing calculators make solving a problem like this very easy. The two functions both have the value -1 at x = -4.

The solution to f(x) = g(x) is x = -4.
