Answer: 20700(.93)^15
Step-by-step explanation:
The domain is the set of allowed input x values for the function. In this case, the domain is the inequality
x > -8 (note the vertical asymptote at x = -8 in which the function never touches)
If you want to write the domain in interval notation, then you would write

which is the interval from -8 to positive infinity (excluding both endpoints)
