Find the equation of the line tangent to at x=1. Give your answer in y=mx+b form as an equation. If b=0, make sure you put +0 after mx. For example, even if your answer is y=3x, type in y=3x+0.

Whats the equation?
If point is just 1, then there is an undefined tangent. Since the tangent will be vertical.
