having difficulty with f(x)=3 times square root of x + 1.

[cathy]

Pls solve if f(x) = 3 times the square root of x + 1. Find the inverse of f graph and its inverse on the same axes.

f(x) = 3 times the square root of x + 1. Find the inverse of f graph and its inverse on the same axes.

To learn how to find the inverse of a function, try here.

To learn how to do the two graphs, try this lesson on graphing radical functions and this lesson on graphing quadratics.

Have fun!
