Question 341473: Hello please help!
Evaluate the exponential function for three positive values of x, three negative values of x, and at x=0. Show your work. State the domain and the range of the function.
f(x) = e^x
Any help is appreciated!
Thanks in advance

You can put this solution on YOUR website! Evaluate the exponential function for three positive values of x, three negative values of x, and at x=0. Show your work. State the domain and the range of the function.
f(x) = e^x
------------
Just do what it says.
At x = 0, f(x) = 1 (anything to the power of 0 = 1)
-------------
x = 1, f(x) = e
x = 2, f(x) = e^2
x = 3, f(x) = e^3
----------------
x = -1, f(x) = 1/e
x = -2, f(x) = 1/e^2
etc
-----------
Most calculators have an ln (natural log) button, and the shift of it is e^x. If your calculator doesn't have that, get one that does.
This is just a calculator exercise.
------------
The domain is all real numbers. The range is f(x)>0
