Question

Evaluate the function below for x=2
F(x)= 4x^3-x^2-5x+7
A. 28
B.25
C.17
D.33

Answer 1

F*2 = 4*2^3-2^2-5*2+7

Multiple: *(2) =
Power: 2 ^ 3 = 8
Multiple: 4 * 8 = 32
Power: 2 ^ 2 = 4
Subtract: 32 - 4 = 28
Multiple: 5 * 2 = 10
Subtract: 28 - 10 = 18
Add: 18 + 7 = 25= (25)

Therefore, your answer is 25.
