Graphing the Function f(x) = 2^x

I plotted 10 different points that satisfied the equation f(x) = 2 ^x starting with 1 as the value of x.

The curved line would cross the x-axis at the point (0, 1) but this curved line segment does not show that because the first value of x that I plotted was 1. The curved line would not cross the y-axis because 2 to the power of 0 is 1 and you cannot get a value of 0 for y using this equation. You could see this better if the scale on the y-axis were smaller. The scale I used was 100 and this makes the beginning part of the line segment difficult to really see.

The values for f(x) start off increasing slowly but get large quite quickly.
