The domain of an exponential function is . The range of an exponential function is .
The graph is throughout its domain and has at the x–axis because the value bx can get very close to 0 but never reach it.
When b > 1, as x grows in the negative direction, y . When 0 < b < 1, as x grows in the negative direction, y .
When b > 1, as x grows in the negative direction, y . When 0 < b < 1, as x grows in the negative direction, y .
