Exponential Graphs:
The graph of 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 is?
By considering the gradient at x = 0, 1, 2, 3, can you predict what the gradient function of
Gradients of and
