Using composition of functions determine if the two functions are inverse of each other

The composition operator (○) indicates that we should substitute one function into another. In other words, (f○g)(x) = f(g(x)) indicates that we substitute g(x) into f(x). If two functions are inverses, then each will reverse the effect of the other. Using notation, (f○g)(x) = f(g(x)) = x and (g○f)(x) = g(f(x)) = x.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
