Please assist me in understanding and solving this problem. Please solve it in Excel and solve it in MATLAB as well and provide the code. Much appreciated

For the piecewise function shown to the right, use IF statements to

calculate f$($x$,$y$)$ for various x and y values. Be sure to text all cases where x

and$/$or y are zero. i$.$e$.$:

Choose enough points between $[-8,8]$ for both x and y and then

plot the graph.

Use IF statements to obtain the correct value.
