Answer:

x = -2, x = 6

Step-by-step explanation:

18 = 3|x - 2| + 6

12 = 3|x - 2|

4 = |x - 2|

4 = x - 2 and -4 = x - 2

x = 6 and x = -2

Evaluating a function means to plug the required value, substituting every x occurrence with that value.

So, you have

$f(x)=3x^2+80x \implies f(2) = 3\cdot 2^2+80\cdot 2 = 3\cdot 4 + 160 = 12+160=172$
