Using exponential function concepts, it is found that the correct option is:
domain: {x | x is a real number}; range: {y | y > –9}; asymptote: y = –9
<h3>What is an exponential function?</h3>
An exponential function is modeled by:
As for the characteristics of the function, we have that:
- The domain is of all real numbers.
- The range is the values of y greater than c, that is, {y| y > c}.
In this problem, the function is:
Hence c = -9, and the correct option is:
domain: {x | x is a real number}; range: {y | y > –9}; asymptote: y = –9
