Plot y = 2x, so it will be a straight line, passing through the origin with a gradient of 2.

The derivative of f(x) is:
f'(x) = 2x

Explanation:
The derivative of any function at any point represents the gradient of the tangent of that function at the point.
The derivative of this particular quadratic function is
This represents a linear function and hence a straight line graph of gradient 2 and intercept the origin.
It is hence drawn as follows :
