Answer:
f(-2)=0
f(2)=12
Step-by-step explanation:
For the first value of x, which is -2, you just need to substitute it to the function given;
f(-2)= 3x+6
= 3(-2)+6 Simplify after,
= -6+6
=0
For the second value of x, which is 2, you just need to substitute it to the function given;
f(2)= 3x+6
=3(2)+6 Simplify after,
=6+6
=12
