To write an exponential function of the form
One exponential function can be written as
Given information:
The graph of the function has y-intercept at 5 and asymptote of
Concept used:
An exponential growth model of the form
Calculation:
Since the function has an asymptote of
The model can be written as
Since the function has a y-intercept at 5, it passes through the point
Substitute
Since there can be many exponential functions satisfying the given condition, consider
When
Thus, one exponential function can be written as
Conclusion:
One exponential function can be written as
