Question 3: Plot the determinant of A against the variable m, over the range -2.5 to 2.5 (hint: use the matlabFunction "f" you created in question 2) and indicate each root using a circle as a marker. Create a graph similar to that shown below (but with a few small differences.) Color-coding scheme for filled circles. NONE, ONE, TONS Red for inconsistent - no solutions. Green to denote the system has a unique solution. Yellow caution! There are free variable(s). There are tons of solutions. (infinite) Number of Solutions Label both axes as shown. Include the title. Color code all three dots (filled circles). Determinant of A -2 -1 0 Parameter m 1 2 Everywhere except at the zeroes, show the determinant curve in green (as shown) to denote the system has a unique solution for all these values of m. Change the face color of the white marker at the root(s) which have no solutions to Red. The system is inconsistent there. Change the face color of the white marker at the root which has an infinite number of solutions to Yellow. The system has a free variable at this value of m. Question 3: Replace the above plot with your completed plot for credit. All three dots must be filled with the proper color code for credit.
