Question

Find the inverse of the function y = f(x). write your solution in inverse function notation, f −1(y). y = 0.3x − 16

Answer 1

`y = 0.3x - 16`


`\text{To find the inverse, interchange the x and y coordinates and solve for y.}`

`x = 0.3y - 16`

`x + 16 = 0.3y`

`y = (x + 16)/(0.3)`


`\therefore f^(-1)(x) = (x + 16)/(0.3)`
