The tangent to the curve `y = e^(2x) ` at (0,1) meets the x-axis at

A

(0, 2)

B

(2, 0)

C

`(-1//2,0)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
We have,
`y=e^(2x) rArr (dy)/(dx)=2e^(2x) rArr ((dy)/(dx))_((0","1))=2`
The equation of the tangent at (0, 1) is
`y-1=2(x-0) rArr 2x-y+1=0`
This meets x-axis at `(1//2,0)`
