Plotting y = e^x is much like plotting y = 2^x. You're absolutely right that e is a number, which is about 2.71. e and pi are both special numbers that get special symbols. They're actually cousins, and you'll learn why they're cousins in trigonometry. Just remember that e is a NUMBER, not a variable. So, the point (1, 2.71) and (2, 7.34) will be on your graph, as will (0,1) and (-1, 0.37). The graphs of e^x and 2^x have the same shape...just a different scale.

yeah, that is the idea. Without calculus, you just make a table of values, Sometimes, you should find the y=0 values for polynomials, since they are useful and important. Don't work, by calculus, you will know how to draw graphs for things like x^(x^2+3x+5) ;)
Oh, and for your other question, yes, e is known as eulers number. That is the "natural" value that is key in things from nuclear decay to chemistry to all of science.
My suggestion for homework is the following website. Very useful!

For your first question, the answer is yes; just construct a table and plot the points, then draw a smooth curve through the points.
x[ -1.....0......1.......2.......3
y[ 1/2....1.....2.......4.......8
As for e: it is an irrational number, equal (approximately) to 2.781828. The procedure for plotting e^x is the same as 2^x.

Yes, you are on the correct path, and "e" is value 2.71828 (base of natural log).

ur rite! but if ur choosing x|-3|-2|-1|1|2| do not forget the zero
