If the tangent to the curve, y = f x = x log e x , x > 0 at a point c , f c is parallel to the line-segment joining the points 1 , 0 and e , e ,then c is equal to :
Options
- Ae - 1 e
- Be 1 e - 1
- Ce 1 1 - e
- D1 e - 1
Correct answer
B. e 1 e - 1
Step-by-step solution
f ' c = 1 + l n c = e e - 1 l n c = 1 e - 1 c = e 1 e - 1
