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%

2^8 2x2x2x2x2x2x2x2=256

Step-by-step explanation:

i'm not sure i quite understand, could you provide more information?

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
