Acollege with a graduating class of 4000 students in the year 2008 predicts that its graduating class
will grow 5% per year. write an exponential function to model the number of students y in the graduating class t years
after 2008.

Step-by-step explanation:

The graduating class grows by 5% each year, this means after 1 year the number of students graduating will be 105% of 4000, or

And after 2 years it will be

and so on. Thus, after years the number of students will be

An exponential function to model the number of students y in the graduating class t years  after 2008 is y = 4000(1.05)^t

The standard exponential function is expressed as:

y = ab^x

If a college with a graduating class of 4000 students in the year 2008 predicts that its graduating class  will grow 5% per year, hence the required exponential equation will be:

y = 4000(1.05)^t

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
