Exercise 25 Page 448

Notice that e^0 means that x=0 in the function y=e^x.

y=1

Practice makes perfect

To draw y=e^x, first push the button Y= and enter the equation in the first row. We can write e on a calculator by pushing 2nd and $÷$.

Having entered the function, we press the GRAPH button to draw it on a coordinate plane.

To find the value of e^0, we can use the trace feature to find the value of the function at x=0. This can be done by pressing 2nd, TRACE, and choosing the value option. Finally, enter 0 and it will give you the value of e^x when x= 0.
