a market researcher tracks the number of people who visits a company's web site each month. the tables shows the data from the last five months of the year.
month web site visitors (thousands)
8 5.74
9 12.00
10 25.07
11 52.40
12 109.42
Part A: which type of function (linear or exponential) best models this situation. EXPLAIN
Part B: describes the approximate monthly growth demonstrated in the table USING WORDS.
Part C: assuming that the growth rate was the same for the entire year, give me an estimate of the number of visitors to the website for month 7. SHOW WORK OR EXPLAIN

Part A: Exponential because it is an exponential function, not a linear function.
Part B: The total number of monthly website visits increases by about 2.1 multiplied by the last month’s total visits.
Part C: 2.73, because 5.74 divided by 2.1 is 2.73 with infinitely repeating 3’s.
this is my answer but i cannot confirm if it is correct.

The varsity basketball team started selling t-shirts online in 1994. the number of t-shirts sold online, s, is modeled by the graph below, where t-0 represents the year 2000. Part A: what is the s-intercept and what does it represent in this situation? What is the t intercept and what does it represent in this situation? Part B: describe the following end behavior of this function as t increases without bond, the function f(t) blank. What does this mean in the context of this situation?
Part C: what is the average rate of change for the function between t=5 and t =7? Show all work. Part D The function g(t) represents the total number of t shirts sold both online and at the basketball games. If the team sold 1000t shirts at the basket ball games each year, what would the equation g(t) look like? How would the graph of g(t) compare to the graph of f(t) The coordinates. On the graph are (0,6)(5,12.5.) (7,22)
the functon f(t)=(1.5)^t+5 is graphed above
