Question

given f(x)=(x^5)+3 and g(x)=5rootx-2
find (f*g)(x)

Answer 1

f(x)=\[x^{5}\]+3
and g(x)=\[\sqrt[5]{x-2?}\]

Answer 2

Assuming this is asking for the composite f(g(x)).

Answer 3

yes

Answer 4

f(g(x))=[g(x)]^5=[(x-2^1/5)]^5

Answer 5

\[[(x-2)^{1/5}]^{5}\]=x-2

Answer 6

Does that look right ???? Someone elses input??

Answer 7

lost me on the 1/5

Answer 8

Looks right to me but you dropped the +3 :)

Answer 9

\[x ^{1/5}=\sqrt[5]{x}\]

Answer 10

wait never mind got you thanks alot

Answer 11

So your final answer should be x+1.

Answer 12

ooops didn't see the +3,that makes a difference. lol

Answer 13

Not by much. You showed the hard part :)

Answer 14

thank you both

Answer 15

Thanks, just reviewed this about a week ago (composites) still learning!

Answer 16

My brain is rusty on most of this. Don't feel bad. It always feels by the end of a class that the stuff from the beginning has been pushed out ;)
