How to plot a function with e^-x?

Hello, I'm trying to plot functions f(x)=100*x^2 and f(x) = 100*x^2*e^-x with time vectors from 0 to 5. I keep getting errors on my function.What is the right way to insert this function in Matlab?

This is my logic:

x = 0 : 0.1 : 5;

y = (100)*(x.^2);

hold on

g = 100*(x.^2)*exp(-x);

plot(x,y,'r',x,g,'b')

grid on

Answer 1

[David Hill]

g = 100*(x.^2).*exp(-x); %looks good, just need .* The rest should work
