Question

if g(x) = x^2 and f(x) = 3x^2-3x-1 then find (g*f) (x)

Answer 1

Hello and Welcome to OpenStudy! :)

(g*f)(x) would mean g(x) * f(x) I think
so plug in g(x) = x^2 and f(x) = 3x^2-3x-1
and get (x^2)(3x^2 - 3x - 1) = ?

Answer 2

and that will be the answer?

Answer 3

try distributing the (x^2)(3x^2 - 3x - 1) can you do that? :)

Answer 4

yeah

Answer 5

tell me what you get then :3

Answer 6

3x^4-2x^3-1x^2

Answer 7

really close :)
try the middle term again
(x^2)(-3x) = ?

Answer 8

oh i am sorry its -2x not -3x

Answer 9

then you are correct :)

Answer 10

ok
