The graph below shows for
Find an estimate of the gradient of the curve at the point where
Draw a tangent to the curve at the point where x = 0.5.
Find suitable, easy to read coordinates and draw a right-angled triangle between them.
Find the difference in the y coordinates (rise) and the difference in the x coordinates (run).
Divide the difference in y (rise) by the difference in x.
Estimate of gradient = 0.6
