Question

Given the polynomial function below, find F(2). F(x) = 5x3 - 2x2 + 3

Answer 1

F(2)=35

Explanation:

we have

F(x) = 5x^3 - 2x^2 + 3

we substitute in X:

F(2)=5*(2)^3 - 2*(2)^2 + 3

F(2)=5*((2)^3) - 2*((2)^2) + 3

2^2=2*=4

2^3=2*2*2=8

so we have

F(2)=5*8 - 2*4 + 3

F(2)=40-8+3

finally we have

F(2)=35
