Nicole 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)=2x+4 and f−1(y)=12y−2f(x)=x+24 and f−1(y)=4y−2f(x)=x7+8 and f−1(y)=7(y−8)f(x)=5x+20 and f−1(y)=15y−20f(x)=5x+11 and f−1(y)=y−115
