Answer:
$95777.5
Step-by-step explanation:
change 7% to decimal = .07
91,000 * .07 = 5370 (annual interest)
5370 / 12 = 530.83 (monthly interest)
530.83 * 9 = 4777.5 (9 months interest)
91,000 + 4777.5 = 95777.5 (initial + 9 months interest)

F(3)= (3-1)^2+ 3(3)=4+9= 13 so the first option is wrong

F(-15)= (-15-1)^2 +3(-15)= 256-45= 211 fourth option is wrong
