Find a point on the curve y = (x – 3)2,where the tangent is parallel to the chord joining the points (3, 0) and (4, 1).


Given: Equation of curve, y = (x – 3)2

Firstly, we differentiate the above equation with respect to x, we get



[using chain rule]



Given tangent to the curve is parallel to the chord joining the points (3,0) and (4,1)


i.e.




2x – 6 = 1


2x = 7



Put in y = (x – 3)2 , we have



Hence, the tangent to the curve is parallel to chord joining the points (3,0) and (4,1) at
