`1.22^(x)`

Explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo

My answer:

Given that:

• A company opened in 1998 and turned a profit its first year, it means that the company has initial value in its function
• The company's revenues increased annually thereafter => it is an exponental function with the base number is greater than 1
• x represents the number of years in operation => which means x is the domain of the company revenue function
• f(x) represents the company's annual revenue

The following functions could model this situation is:

B. f(x) = 884 •
`1.22^(x)` where:

884 is a profit its first year

1.22 growth rate in revenue

x represents the number of years in operation

Hope it will find you well.
