Help plz :)

answer:

f(x) = and g(x) = 1/x

Step-by-step explanation:

(f ° g) (x) = f(x) ° g(x)

by putting the values of f(x) and g(x) and then multiplying we will get

X (1/x) = x ( x will be eliminating from denominator and numerator)

let us take the 2nd option.

by multiplying the value of f(x) and g(x) we will get 2/x X 2/x =

4/, but it is not the answer.

here showing you two options.

you can cross check with the other options. but none of the options will give you the required answer. so answer will be 1st option.

this process is called trial and error method.

hope it helps!

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
