Question

Gabriel claims that each of the following pairs of functions are inverses. However, ONE of the pairs are NOT inverses. Pick the pair of functions that are NOT actually inverses.

f(x)=5x+20f(x)=5x+20 and f−1(y)=15y−20f-1(y)=15y-20
f(x)=3x+9f(x)=3x+9 and f−1(y)=13y−3f-1(y)=13y-3
f(x)=x+37f(x)=x+37 and f−1(y)=7y−3f-1(y)=7y-3
f(x)=x5+1f(x)=x5+1 and f−1(y)=5(y−1)f-1(y)=5(y-1)
f(x)=5x+11f(x)=5x+11 and f−1(y)=y−115
