Investigating the Gradient of a Graph of the

Form ‘y=x3

Aim:

To find a relationship between the gradient of ‘y= x3’ and its formula. Thus working out the gradient function.

In this case I will measure the gradient at, –4, -2, 3, and 5.

Calculations

To find the gradient on a certain point of the ‘y=x3 graph you draw a tangent from a point. Then you form a right-angled triangle on the tangent and find the gradient as for the ‘y=ax’ graph. (As shown on graph)

e.g.
