You are given two functions f(x) = x + 3 and g(x) = x2 + 2. (a) Show how you can define the two functions in MATLAB and plot them on the same figure with the appropriate labels to the axes and legend. Sketch your answer of the figure. (b) Show how you can determine the intersection point(s) of the two functions. (c) Write the MATLAB code to find the area enclosed by the two functions. Display the answer in the Command Window in three decimal points together with the unit of m2. Use the hexadecimal value of 0B2 to display the superscript 2. 70
