W t y and in a two column table (3 rows) 16) [5 pts) Plot y=x2+2x+3 for --10:10. Insert a title for the plot and label both x and y axis. (choose a small step size to see a smooth curve). 17) [5 pts) Plot y3sin(x+/6) and 2-0.5cos(x) on the same figure for x-2:20:2. Insert a legend to differentiate the two plots. Use different colors and markers in each plot. 18) [5 pts) Use 'subplot' to plot In(x), log.ox), e' on a single figure by dividing the figure into sub plots. Interval x-200/20:21. 19) [10 pts) Create a figure containing three subplots. Create two subplots for sin(x) and cos(x) across the upper half of the figure and a third subplot which includes both sin(x) and cos(x) that spans the lower half of the figure. Add titles to each subplot. Add a legend to the third subplot
