I am trying to plot y=1-e^{-5x}. but matlab keeps spitting out the wrong plot. Please let me know what I am doing wrong.
My Code:
>> syms x y
>> y = 1-(exp(-5*x));
>> fplot(y)
The plot is supposed to look like this

Ran in:
syms x y
y = 1-(exp(-5*x));
fplot(y, [-.2 3]) % need right interval for x (or set ylim([-2 1])
grid on

If I understand correctly, I have to calcualte 0.2 so that the x-intercept wil roughly be zero?

From my understanding, I can set my ylim to anything and my code will now return a correct graph. My interval set points have to be exactly correct otherwise my graph will shift along the x-axis.
