You've almost got it. Two things to fix:

1. MATLAB is a case-sensitive language (that upper and lower case matters), so you must use upper-case "X" consistently, and "plot" is all lower case.
2. The "^" (raise to the power) operator is for square matrices. To computer a per-element raise to the power, use ".^" instead.

 X=0:0.1:3
 Y=2.^X
 plot(X,Y)
