Answer & Solution

Correct Answer

(A) 3x-y=33

Step-by-step Solution

Detailed explanation

The equation of the parabola,  y2=4x The equation of the normal to the parabola,  y2=4ax at am2,-2am is y=mx-2am-am3 Here, a=1, the equation of the normal becomes,  y=mx-2m-m3 …I Since the normal is perpendicular to the…
