Question

Find the inverse of the function.
y=3x–5

Answer 1

Explanation:

it means that x has now to be the result variable, and y the input variable.

so,

y = 3x - 5

y + 5 = 3x

x = (y + 5)/3

and as a final touch, to make the inverse a "normal function", we rename x to y and y to x and get

y = (x + 5)/3

as the inverse function
