Given information
We are given the parabolic equation that passes through the point .
Step-by-step explanation
Step 1.
Note that all points on the parabola are of the form
Assume that the tangent at passes through
We know that the slope of tangent at any point is the derivative at that point.
Differentiate , To get ,
Therefore, the slope of tangent at
Since the tangent passes through the points and , We can write the slope of the tangent as
