xaxis = [0:0.5:2]; %x-axis
plot(xaxis,f) %plotting function //DOESN'T WORK

"Doesn't work" does not explain the problem. You get an error message:
Error using plot
Invalid data argument.
This is an important hint. The 2nd input is a function handle, but Matlab expect numerical values.
For a solution see Star Strider's answer.

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.
