Question

Given the polynomial function below find F(2)

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

Answer 1

35

Explanation:

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

f(2)=5x2^3-2x2^2+3

=5x8-2x4+3

=40-8+3

=40-5

=35

Answer 2

35

Explanation:

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

Let x=2

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

= 5*8 -2(4) +3

= 40 -8+3

= 32+3

= 35
