Having issues getting my nonlinear function to plot.
f = @(x) 2.^x-5*x+2;%Given Function
xaxis = [0:0.5:2];%x-axis
plot(xaxis,f)%plotting function //DOESN'T WORK

yeah sorry about that. This is my first time using a forum like this and I'm still relatively new to coding. Thanks for insight!

Ran in:
It works if you give ‘f’ a vector to work with —
f = @(x) 2.^x-5*x+2;%Given Function
xaxis = [0:0.5:2];%x-axis
plot(xaxis,f(xaxis))%plotting function //DOESN'T WORK —> YEs, IT DOES!
Experiment to get different results.
