part a
identify the function type in the graph, and then describe a relationship that could be modeled by the function represented by the graph.
part b
then, identify and interpret the key features of the function in the context of the situation you described in part a.

Step-by-step explanation:

part A.

It's a decreasing exponential function.

A relationship could be: Tom has 3 cookies. Each day, he eats half of the cookies left from the previous day.

part B.

y-intercept is the number of cookies he starts with, or 3. The rate that the cookies is decreasing is 1/2.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
