Q4 of 149 Page 16

The point on the curve y2 = x where tangent makes 45° angle with x-axis is

Given that y2 = x


The tangent makes 45° angle with x-axis.


So, slope of tangent = tan 45° = 1


∵ the point lies on the curve


∴ Slope of the curve at that point must be 1






And


So, the correct option is B.
