Does this graph represent a function? Why or why not? A. No, because it fails the vertical line test.
B. Yes, because it has two straight lines.
C. No, because it is not a curve.
D. Yes, because it passes the vertical line test.

A

Step-by-step explanation:

it fails the vertical line test which is a test to see if a graph is a function

bottom left

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
