Question

f(x)=7/x-2 and g(x)=7/x+2 find (fog) and (gof) are they inverses of each other?

Answer 1

WAT IS X SO I CAN DO IT

Answer 2

By inspection, they don't look like inverses, but to do the compositions first replace the x in f(x) with function g and simplify; then replace the x in g(x) with function f and simplify. If both yield x, then they are inverses.

Answer 3

@esavanessa This is Calculus.
