Question

Let g(x)=x/(8-x) and h(x)=x^3-2x^2+8. Calculate the function g(h(t)).

so confusing...

Answer 1

plut t in for x in the h equation

Answer 2

what do you get?

Answer 3

you get the equation but just with a t instead of an x right?

Answer 4

yes good

Answer 5

now take that equation the entire thing and write it in the g formula whereever you see an x

Answer 6

ok and thats the final answer?

Answer 7

yes! g(h(t))=(t^3 -2t^2+8)/(8-t^3+2t^2-8) notice the signs change on the bottom because it was (8-x) so the -x made all the signs change now the 8's cancel

Answer 8

ok thank you so much!

Answer 9

wait one minute i'll make sure it cannot be simplified

Answer 10

ok

Answer 11

no its good :)

Answer 12

awesome! Im going to test it out right now
