Question

Find the inverse function of f(x)=square root 3x+5

Answer 1

`(x^2-5)/(3) =y\\`

Explanation:

since it is f(x), we can assume that

`f(x)=y`

`y=√(3x+5\\)`

to find the inverse of a function you just swap the x and y and then solve for y

`x=√(3y+5\\)`

`x^2=3y+5`

`x^2-5=3y`

`(x^2-5)/(3) =y\\`

Hope that helps :)
