# Issue with plotting variables with ranges

Hi, I am trying to plot these three equations. They should form a sort of triangle. The main issue I am having is trying to enter the equations, which have variables with ranges. % x is x/c
assume(0<=x<=.1)
Cpu1=1-300*(x)^2
Here is me trying the first one, but it doesn't give me any values. Not sure the best way to do this. Any help would be greatly appreciated!

Here is how to start this:
N = 200; % Number of data points to be genearted and calculated to plot
xc=linspace(0, .1, N);
Cpu=1-300*xc.^2;
xc2 = linspace(.101, 1, N);
Cpu2 = -2.777+2.777*xc2;
xc3 = linspace(0, 1, N);
Cl = 1-.95*xc3;
% the rest is to plot the above data
plot(xc, Cpu, 'b-o'), hold on;
plot(xc2, Cpu2, 'r-x')
plot(xc3, Cl, 'k-')
Good luck
