Determine which of the following graphs does not represent a function. (Help me ASAP)

Mathematics
1 answer:
dedylja [7]2 years ago
7 0

Answer:

D

Step-by-step explanation:

one way to determine whether or not something is a function is to use the vertical line test

You can draw vertical lines all along the figure and if the same vertical line touches 2 parts of the graph we know this is not a function due to there being 2 outputs for the same x value

d is a vertical line and therefore will not pass this test

I need an explanation for the problem 4v2=-12v-9. I don't understand why it factors into 4v+3 and 4v+3
kirza4 [7]

Answer:

The factors are 2v+3,2v+3.

The factors are not 4v+3,4v+3

Step-by-step explanation:

Equation is 4v^2=-12v-9.

This equation can be written as follows:

4v^2+12v+9=0

Here,

12v=6v+6v

Therefore,

4v^2+6v+6v+9=0\\2v(2v+3)+3(2v+3)=0\\(2v+3)(2v+3)=0

So, the factors are 2v+3,2v+3.

The factors are not 4v+3,4v+3

X =37.50/ 5.25=7.14

But since she can't buy part of a ticket, Jan can buy 7 tickets
