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.

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

The solution to f(x)=g(x) is (-7, -8)

Functions and graphs

Given the functions

  • f(x) = 4x + 20
  • g(x) = 2x + 6

If the functions are equal then;

4x + 20 = 2x + 6

4x - 2x = 6 - 20

2x = -14

x = -7

Since y = 2x + 6

y = 2(-7) + 6

y = -14 + 6

y = -8

Hence the solution to f(x)=g(x) is (-7, -8)
