I have never encountered a problem like this and am a bit confused.
Function $f$ satisfies:
Find an equation for the tangent line to the curve $y=f(x^2)$ at point $(x,y) = (3,7)$.
I don't know where to start. I drew a graph of the points related to the slope of the derivative but that doesn't really help me, and I don't understand the concept of $y = f(x^2)$.
A point in the right direction would be great, thank you for any help!
