3. Determine the maxima and minima of the function f(x)=((x2)4+1.8)2.3x2 First create an anonymous function, then fplot in the domain 0x5. Inspect the fplot to determine the boundaries of x for each maxima and minima. Use those boundary values in the fminbnd cmd to calculate the approx maxima and minima. Then use the hold on, plot, num2str, and text cmds to add the maxima and minima coords to the plot. After all plotting and fplotting cmds use the savefig and print cmds to save the figure. Refer to previous labs and the example code and image (below). 4. Determine the maxima and minima of the function f(x)=3xsinx+x41+31 First create an anonymous function, then fplot in the domain 0x14. Inspect the fplot to determine the boundaries of x for each maxima and minima. Use those boundary values in the fminbnd cmd to calculate the approx maxima and minima. Then use the hold on and plot cmds to add the maxima and minima to the plot. After all the plotting and fplotting cmds use the savefig and print cmds to save the figure.
