Question

please help fast give option​

Answer 1

Step-by-step explanation:

slope of the curve y = x² + 4x + 1 is,

dy/dx = 2x + 4

therefore slope dy/dx at x = -1 => 2(-1) + 4

=> -2 + 4 => 2

slope of normal at this point = -1/2

[ m1×m2 = -1 if two lines are perpendicular and normal is perpendicular to the tangent ]

option b
