Question

Let f(x)= x^2+6 and g(x)=x+8/x
Find (g*f)(4)

Answer 1

g(f(4))=?
to find it,first find f(4) which is
f(4)=4^2+6
f(4)=16+6
f(4)=22

then g(f(4))=g(22)=22+8/22
=22+0.36
=22.36

Answer 2

ya got it?

Answer 3

Or in fractions:

\[\huge \color{green}{g(f(4)) = \frac{246}{11}}\]

Answer 4

No ! lol. The answer choices are fractions so it makes it kind of difficult. Are you saying the anwser is 22.36 ?

Answer 5

ya

Answer 6

the fraction is 246/11

Answer 7

Answer 8

as the answer choices

Answer 9

Is it?

\[(g \times f)(4)\]

Answer 10

yes

Answer 11

There is something wrong in the question I think..
