Write and graph exponential functions to model the number of students at school A and at school B as a function of number of years. In about how many years will the number of students at both schools be approximately the same? Explain how you can use a graph to determine the answer school A:240 decreasing at an annual rate of 2%
school B:180 increasing at an annual rate of 3%

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
