f=@(x) (x.^3-3*x.^2-4*x+12)/(x-2) ; % Insert function f here g=@(x) (x.^2-4*x)/abs(x-4) ; % Insert function g here x=[1.5:0.01:2.5]; % Refer to Step 2 above for the next 3 lines y1=x; fp=plot(x,y1); title('Graph of f'); % DO NOT CHANGE COMMAND ON THIS LINE figure; % DO NOT CHANGE COMMAND ON THIS LINE x=[3.5:0.01:4.5]; % Refer to Step 4 above for the next 3 lines y2=x; gp=plot(x,y2); title('Graph of g'); % DO NOT CHANGE COMMAND ON THIS LINE
