Answer with Step-by-step explanation:
We are given that


a.We have to find g(f(x))


b.We can see that
f(x) is logarithm function and g(x) is linear function.
But , the composition function gof(x) is also logarithmic function.
The composition function gof(x) is 3 times the function f(x).
3/5=6/10 so Naomi got 138.
Luke got 69.
And Natalie got 23.
8 is the missing number
Let’s say x is 2,
3(2)+8=14
8(2)-2=14
