The exponential constant e
www.mathcentre.ac.ukYou should also check that you can evaluate negative and fractional powers of e such as e1/2 = 1.649 and e−2 = 0.135 Theexponentialfunction If we write y = ex we can calculate the value of y as we vary x. Values obtained in this way can be placed in a table. For example:

If p > 0, then the graph starts at the origin and continues to rise to infinity. (In particular, if p > 1, then the graph is concave up, such as the parabola y = x2.If p = 1, the graph is the straight line y = x.
