Question

characteristics of rational functions algebra 1 help
i answered them, but i just dont know how to do these....if you just give answer i appreciate but if you show step by step then im more thankful the i dont ahve to ask again xD

Answer 1

wait

Answer 2

Answer 3

so from what i know, if it going downwards or decreasing it should be a x > then something and if it increases then its X < but i just... i really dont know how to do this since they didnt really explain how to do this.

Answer 4

Look at the first graph from left to right.

As x gets larger, the y-values are getting smaller.

This is happening on both sides of the vertical asymtote x = -2.

So, what is your thinking that the answer would be x > -2 ?

Answer 5

Answer 6

well

Answer 7

when i was reading on how to do it, it said if the values get smaller, its X > and if it gets bigger then its X < but you know that didnt really seem right to me... reason why im asking for help since i wanna pass this

Answer 8

>>if you show step by step then im more thankful

I can't do this unless you work with me.

Three of the 4 problems appear to be incorrectly answered.

Answer 9

I think it would be helpful to toss out that guideline and look at the graphs.

On the first graph, the values of y are decreasing. There is no interval over which the graph is increasing.

Reading from left to right, the values of y are getting smaller. Look at the graph and see if you agree.

Answer 10

ok

Answer 11

so i looked into it more and is this true?
If slope is positive ,then graph would be increasing.
If slope is negative,then graph would be decreasing.

Answer 12

For lines, yes.

These problems do not require that you calculate slope.

Just look and see what y is doing as x gets larger.

There are no calculations to make here.

Answer 13

On the first graph, the graph appears to be increasing for NO values of x.

Answer 14

just wondering would question 2 and 3 both be A?

Answer 15

I will look.

This Khan Academy video is good for helping you understand the concepts of this:

Answer 16

The y-values are negative below the x-axis.

Answer 17

There are no increasing portions of the graph here.
