A biologist tracked the growth of a strain of bacteria, as shown in the graph.


A. Explain why the relationship represented by the graph is a function.


B. Suppose there was the same number of bacteria for two consecutive hours. Would the graph still represent a function? Explain.

Answer:

Part A -> Function

Part B -> Function

Step-by-step explanation:

Concept

A relationship is a function only if there's a single y value corresponding to an x value. It can have the same y value for different x values but it must not have multiply y values for a single x value.

Below is an example

Function                                        Not a Function

x           y                                        x           y

1           5                                        1            5

2          6                                        2           7

3          5                                         1           6

Part A

Looking at the given graph, we see that the relationship has a single y value corresponding to an x value and so it is a function.

Part B

If there was the same number of bacteria for two consecutive hours it would mean the same y value for different x values. So, it would still remain a function.
