(e^(-2x))-2x+1

I want to plot the above equation in Matlab but i don't know how to plot.

Answer 1

[Turlough Hughes]

Here's a plot of the function over the range of x = -2 to +2.

x=linspace(-2,2,1000);
y=exp(-2*x)-2*x+1;
plot(x,y)

I used linspace to generate 1000 values for x, which are equally spaced from -2 to 2, and then subbed these into your equation .

Another easy way to plot it:

fplot(@(x) exp(-2*x)-2*x+1)

or

fplot(@(x) exp(-2*x)-2*x+1, [-2 2])

to plot over the same range.
