4) Plot the following functions for x[0,(4)2] using subplot, label the horizontal and vertical axes, and include a title: a) f(x)=1+cosx b) f(x)=1+cosx; and c) f1(x)=cosx,f2(x)=1+cos2x and f3(x)=f1(x)f2(x), for x[0,10], with all three curves in one plot. Use different line types and/or colors to differentiate them, and use legend to indicate which is which. Note: Each function must be written as an anonymous function, exactly as written
