1.3.5 Inverse functions and their graphs (A-level only)

If f(a)=bf(a)=bf(a)=b, what does the inverse do to bbb?

A

Under reflection in y=xy=xy=x, the vertical asymptote x=ax=ax=a becomes the horizontal asymptote y=a\boxed{y=a}y=a​.

B

It gives f−1(b)=af^{-1}(b)=af−1(b)=a.

C
  • x≥0x\ge 0x≥0
  • x≤0x\le 0x≤0
D
