Find f(-2):
F(x) = 2x^3 – 3x/x^2 + 1

4.4
2
-2
-4.4

Answer 1

f(-2) mean thet just substitute the -2 in place of x

right ?

Answer 2

Yep

Answer 3

That is what I did.

Answer 4

so

f(-2)= (2*(-2)^3 -3*(-2))/((-2)^2 +1) =

do you can calculi it ?

Answer 5

f(-2)=( 2*(-8) +6)/(4+1) = -10/5 = - 2

Answer 6
