Astudy estimates that the cost of tuition at a university will increase by 2.8% each year. the cost of tuition at the university in 2015 was $33,741 the function b(x) , models the estimated tuition cost , where x is the number of years since 2015.
finds the expression that completes the function b(x)

The complete expression for the compounding tuition fee function is

Using the compound interest relation :

Where ;

The function b(x) can be written as :

Therefore, the expression for the function b(x) is :

so, the cost will increase 2.8% per annum... so that simply means is a compound interest rate, so let's use the compound interest formula for this one.

your answer is -9

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
