Asked by maham237 @ 18/12/2020 in Mathematics viewed by 367 People

find f^-1. Determine whether f^-1 is a function.

Answered by maham237 @ 18/12/2020

The inverse of

f(x) = (7-8x)^2

is ............. f-1(x) = 1/8 *(7 ±sqrt(x))

If we plot this graph We can easily see it is not a function

(Fails the vertical line test)
