Question

Help with functions?!

f(x) = 3x^2-4
g(x)=x^2-3x-4

find (f/g)(-1)

Answer 1

so where it says "f", put in everything after the equals sign for the f(x) function (hint: 3x^2 - 4) and then where it says g put in everything after the g(x) function (x^2 - 3x - 4)

Answer 2

so it just becomes the fraction of 3x^2-4 / x^2-3x-4, and then solve the fraction and multiply by -1?

Answer 3

you lilly, are a genius. absolutely spot on.

Answer 4

if it were f+g is it the same, just (3x^2-4) times (x^2-3x-4)?

Answer 5

that would be f TIMES g

Answer 6

ok. THANKS!!

Answer 7

f + g is exactly as it looks (3x^2-4) + (x^2-3x-4)

Answer 8

ok, thanks again!

Answer 9

what about f^g ?
