Which explains why the graph is not a function? It is not a function because the points are not connected to each other. It is n

MrRa [10]

A function is a relationship between two sets of variables, the domain and the range, in which each value of the independent variable (the domain) is associated with exactly one value of the dependent variable (the range). Therefore, a graph is not of a function when there are two different values of y for a single value of x.

Ksju [112]

Answer:

<h2><u>8117</u></h2>

Step-by-step explanation:

<em>by considering</em> 2 + 3 = 95

3² = 9

2 + 3 = 5

<em>by considering</em> 4 + 5 = 259

5² = 25

4 + 5 = 9

<em>by considering</em> 6 + 7 = 4913

7² = 49

6 + 7 = 13

<em>by considering</em> 8 + 9 = ????

9² = 81

8 + 9 = 17

∴ <u>8 + 9 = 8117</u>
