Outline

Complete the implementation of the the inversePlot function. You will be plotting a function, its inverse, and the reflection line (y=x) all in the same figure using the fplotfunction. You will also want to ensure that the x-axis and y-axis are equally scaled in the figure by using the command axis equal (this is included in the template for you).

The function inversePlot plots three curves, which must be plotted in the order stated below.

Graph the function y=x2 using the fplot function, from x = 0 to x = 2.

The curve should be displayed using a blue line.

On the same set of axes as the first curve, graph the inverse function of y=x2 using fplot along the same domain as the first graph. Note that this function has an inverse given the domain does not include negative values.

The curve should be displayed using a red line.

On the same set of axes as the first curve, graph the function of y=x using fplot along the same domain as the first graph.

The curve should be displayed using a dashed black line.

Input variable: n/a this function has no input variables.

Output variable: n/a this function has no output variables.

Notes:

To put multiple plots in the same figure, we can use the hold on and hold off commands. After typing hold on all fplot functions will be plotted in the same figure. Typing hold off stops this behaviour, and reverts MATLAB back to its default behaviour.

Read through section 7.1 and 7.5 of the 'Introduction to Programming in MATLAB' for further information on plot customisation and multiple plots.

Although the inversePlot function does not have any output variables, the graph will be examined to determine if the correct values have been plotted.

Do not use the figure command in your solution -- this will confuse AMS, which needs to manage the plotting environment to examine your results.
