Exponential Graphs: ax
The graph of f(x)=ax is shown in blue, together with its tangent and gradient at a sample point in red.

By considering the gradient at x = 0, 1, 2, 3, can you predict what the gradient function of f(x)=ax is?
Gradients of ax and ex
Compare the graph of f(x)=ax with the graph of its gradient function, f(x).
Adjust the value of a till the the two curves coincide.
