Functions: Formal Definition , Inverse, exponential and logarithmic

- Definition of a function.

2. General concept of the inverse of a

function and how the domain of the

function may need to be restricted (in

order to obtain a one-to-one function)

to ensure that the inverse is a function.

3. Determine and sketch graphs of the

inverses of the functions defined by

𝑦 = 𝑎𝑥 + 𝑞;

Focus on the following characteristics: domain and range intercepts with the axes,

turning points, minima, maxima, asymptotes (horizontal and vertical), shape and

symmetry, average gradient (average rate of change), intervals on which the function increases /decreases.
