[SOLVED] Tangent Line
Find all tangent lines that are tangent to Y=x^2 and go through the point (2,3)
At first I thought I knew how to do this problem, I found the derivative of the equation got:
y' = 2x ; then I plugged in x=2 to find the slope of the tangent however then i realized this is not the correct point to plug in because this is not the point that the line is actually going to be hitting the original graph at; I don't know how you would find this said point to plug in for x to get the slope can anyone steer me in the right direction
