Question

Given that f(x)=2x^3+x-3, evaluate the function f(-2). A.) 11 B.) -69 C.) -21

Answer 1

F(x)=2x³+x-3
f(-2)=2(-2)³+(-2)-3
f(-2)=2(-8)-2-3
f(-2)=-16-2-3
f(-2)=-18-3
f(-2)=-21. As a result,C is your final answer. Hope it help!

Answer 2

F(x) = 2x^3 + x - 3
f(-2) = 2(-2)^3 +(-2) -3
f(-2) = 2(-8) -2 - 3
f(-2) = - 16 - 2 - 3
f(-2) = -21
