If f(x) = √3x+2, what is the equation for f^-1(x)

Answer:
The correct answer is D) f(x) = (x^2 - 2)/3
Step-by-step explanation:
To find an inverse function, swap x and f(x) and then solve for the new f(x). That will be the new inverse function.
f(x) = √3x+2
x = √3f(x)+2
x - 2 = √3f(x)
x^2 - 2 = 3f(x)
(x^2 - 2)/3 = f(x)
