Given the function f(x) = 3x - 2] + 6, for what values of x is f(x) = 18?
x= -2, x= -8
x = -2, x= -6
x = -2, x = 6
x = -2, x = 8

x = -2, x = 6

Step-by-step explanation:

The correct question is

Given the function f(x) = 3|x – 2| + 6, for what values of x is f(x) = 18?

we have

For f(x)=18

substitute the value of f(x) and solve for x

Subtract 6 both sides

Divide by 3 both sides

Solve the absolute value

First case (positive value)

Adds 2 both sides

Second case (negative value)

Multiply by -1 both sides

Adds 2 both sides

The solutions are x=-2, x=6
