tangent line is the first derivative

wait so just find the derivative?
OpenStudy (anonymous):
yep that will give you the equation then plug in your value
OpenStudy (anonymous):
Take the derivative, evaluate at x=2. Use that value as the slope, and (2,f(2)) as a point on the line to get an equation of the line.
