Joe is researching the cost of going to college. He sees the table shown. Joe wants to create a mathematical model, f(x), where x represents the number of academic years since 1979-1980, to predict future cost of tuition and fees using data in the table.
Which type of function will most closely match the data? A) decreasing linear function B) increasing linear function C) exponential decay function D) exponential growth function
D) Exponential Growth Function
This is because in a linear equation, there is a constant 'slope' of how something increases like a specific amount but in this equation, the growth is by a specific percentage which allows for a difference in the amount each year. For example, a linear function would be if it increased by four dollars every year, so 2, 4, 6, 8,etc. But a exponential function would be like if it increased by for percent each year, so 2, 2.16, 2.25, 2.34, etc.
D) exponential growth function

What is division?
Division in maths is the process of breaking a number up into equal parts, and finding out how many equal parts can be made.
For example if 200 apples are to be shared by 25 students, the number if apples that will get it each students is calculated as;
