Sketch the graph of
f( x ) = e^{x }.
Solution
Let's build up first a table of values for this function.
x
-2
-1
0
1
2
f(x)
0.1353...
0.3679...
2.718...
7.389...
To obtain these evaluation (with the exception of x= 0 ) you will have to use a calculator. Actually, that is part of the point of this instance. Ensure that you can run your calculator & verify these numbers.
Following is a sketch of this graph.
Notice that this is an increasing graph as we have to expect since e = 2.718281827.... 1.
