The number of stores opened by a coffee company can be modeled by the exponential function graphed on the grid, where x is the number of years since 1992.
an exponential curve starting at (0,400) with the line curving sharply up and slightly right.
What are the domain and range of this graph?
The domain of the graph represents the number of years since 1992, so it would start at x = 0 and continue indefinitely. Therefore, the domain is x ≥ 0.
The range of the graph represents the number of stores opened by the coffee company. Since the graph starts at (0,400) and curves sharply up, it implies that the number of stores opened is also increasing. Therefore, the range would start at y = 400 and continue indefinitely. Therefore, the range is y ≥ 400.
