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?
