Question
The equation of the tangent to the curve y = x + 
, that is parallel to the x-axis, is
, that is parallel to the x-axis, isOptions
A.y = 1
B.y = 2
C.y = 3
D.y = 0
Solution
Parallel to x-axis 
⇒ x = 2 ⇒ y = 3
Equation of tangent is y - 3 = 0(x - 2) ⇒ y - 3 = 0
⇒ x = 2 ⇒ y = 3
Equation of tangent is y - 3 = 0(x - 2) ⇒ y - 3 = 0
