The table shows values for functions f(x) and g(x) .
mart [117]

Answer:

-3 and -4

Step-by-step explanation:

f(x) = g(x) will be the input or x value at which f and g have the same output or y value. Look in the table where two numbers repeat right next to each other.

−6 −4 1

−5 0 2

−4 4 4

−3 8 8

−2 12 16

−1 16 32

0 20 64

The solution to f(x)=g(x) is both x = -4 and x=-3.
