Question

Find the inverse of each of the given funcions fo) = 4x-12 51x)= DONE o

Answer 1

Let y be f(x)

$\\ \sf\longmapsto y=4x-12$

Swipe the values

$\\ \sf\longmapsto x=4y-12$

• Isolate y

$\\ \sf\longmapsto 4y=x+12$

$\\ \sf\longmapsto y=\dfrac{x+12}{4}$

$\\ \sf\longmapsto y=\dfrac{1}{4}x+3$

Hence.

$\\ \sf\longmapsto f^{-1}(x)=\dfrac{1}{4}x+3$
