Find f(3) if
f(x) = x^3+ 2x^2 -x - 1
HELP ASAP

f(3) = 41

Step-by-step explanation:

When we have something like f(3), which is f of 3, we just plug 3 in for x. Wherever you see an x, replace it with 3.

f(x) = x^3+ 2x^2 -x - 1

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

     = 27 + 2(9) - 3 - 1

     = 27 + 18 - 4

     = 41
