Part 1:
The table below displays a small portion of the infinite domain of the exponential function y = 2x. Use the values for the domain to determine its corresponding range.
x -2 -1 0 1 2
y
Part 2:
Graph the exponential function y = 2x. using the table from Part 1.
Part 3:
Think about it:
A. In the table of domain and range values, we used -2 as our minimum x-value. Are there values of x for the function that are less than -2?
B. Locate the smallest y-value on your table. Compare it with the y-values of your graph. Is the table a complete representation of the range of the function?
C. Is there a limit to the minimum or maximum values of x? Is there a limit to the minimum or maximum values of y?
