Find a point on the curve y=x^2+x , w...

Find a point on the curve `y=x^2+x` , where the tangent is parallel to the chord joining (0, 0) and (1, 2).

Text Solution

Verified by Experts

The correct Answer is:
`(c, f(c)) => (1/2 , 3/4)` is the point

Let: `f(x)=x^{2}+x`
The tangent to the curve is parallel to the chord joining the points `(0,0)` and `(1,2)`.
Assume that the chord joins the points `(a, f(a))` and `(b, f(b))`.
$$ \therefore a=0, b=1 $$ A polynomial function is continuous and differentiable at each point.
