3. Define a variable y from 0 to 20 with steps of 0.2. Also, define the time variable t from 0 to 10 with steps of 0.1. Plot the graph of y v/s t. a. Label the x-axis and y-axis. 4. Write the following code in MATLAB and answer the questions that follow: x linspace(0,1); y 1 x +x. 2/2 - x. 3/6; exact exp(-x); figure plot (x, y) figure plot (x, exact) hold on plot (x,y,'r-.') hold off % create new figure window for plotting y % create new figure window % causes subsequent curves to be added to current figure % returns to normal plotting mode" a. What is the function of linspace? b. What is the function of figure? c. What is the function of hold on and hold off? 3. Define a variable y from 0 to 20 with steps of 0.2.
