Question

2. Use the subplot command to make two plots of the function f(x) = (x + 1)(x - 2)(2x – 0.25) - et one graph for 0 < x <3 and the other for 3 < x < 6. Use a logarithmic scale for the y-axis. Include a plot title (for each subplot), and label both aris(for each subplot).

Don't use fplot command. Matlab code. Write out code please, don't make it a screenshot.

subplot(2,1,1);
x=0:0.01:3;
y1=(x+1).*(x-2).*(2*x-0.25)-exp(x);
semilogy(x,y1);
xlabel('X-axis');
ylabel('Y-axis log scaled');
title('Plot of funcion in 0 to 3');
subplot(2,1,2);
x=3:0.01:6;
y1=(x+1).*(x-2).*(2*x-0.25)-exp(x);
semilogy(x,y1);
xlabel('X-axis');
ylabel('Y-axis log scaled');
title('Plot of funcion in 3 to 6');
