Abiologist 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.

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.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
