The table shows values for functions f (x) and g (x).

x f (x) = 4x+20 g (x) = 2x+6

-6 - 4 1

-5 0 2

-4 4 4

-3 8 8

-2 12 16

-1 16 32

0 20 64

What is the solution to f (x) = g (x) ?

Select each correct answer.

-6

-5

-4

-3

-2

-1

0

-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.
