Answer:
136
Step-by-step explanation:
plug in -4 in the x
f(-4)=3(-4)^2 - 8
f(-4)=-12^2 - 8
f(-4)=144-8
f(-4)=136
Done!
Quadratic polynomial is x^2 - x - 20
Answer: 6
6+6=12 12+6=18 thus 6 times 3 is 18
$17
17+11 = $28
28+11 = $39
39+11 = $50
17 + 11(n-1) $$
n-1 because removes the first class of $17
