Hey so do you know how to start this problem?

OpenStudy (anonymous):

aka do you know what an inverse of a function is?

OpenStudy (anonymous):

You can find an inverse by switching around y and x.

OpenStudy (anonymous):

[y=\sqrt{2x+3}\]

OpenStudy (anonymous):

\[y=\sqrt{2x+3}\]

OpenStudy (anonymous):

\[y^{2}=2x+3?\]

OpenStudy (anonymous):

yup so like what greenglasses said all you have to do to find the inverse function is to switch the x and y

OpenStudy (anonymous):

\[y ^{2}-3=2x\]

OpenStudy (anonymous):

You need to isolate for y in the new equation though.
