if 3/4 are boys, then 1/4 (the rest of the school population) are girls.

QveST [7]

Answer with Step-by-step explanation:

We are given that

f(x)=log_3(x)

g(x)=3x

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).
