G6 The function a^x

	Content	Additional information
G6.1	using a calculator to find values of such a function	the laws of logarithms will not be required
G6.2	using a calculator log function to solve equations of the form $a^{x} = b$ and $e^{k x} = b$

	Content	Additional information
G7.1	understanding that $e$ has been chosen as the standard base for exponential functions	knowing that the gradient at any point on the graph of ${y = e}^{x}$ is equal to the $y$ value of that point
