Answer 1

Answer 2

whats your question?

Answer 3

thats my question i have choices for each

Answer 4

first choices are 5x^2 ,2x
second choices for the second question is -5x^3 ,3x^2 ,4x

Answer 5

If you have an odd exponent you will have an odd function if you have an even degree exponent than you will have an even degree function, odd degree functions have different end behavior even degree functions have same degree behavior

Answer 6

im confused

Answer 7

What are you confused about?

Answer 8

i dont understand how to do this

Answer 9

You have to figure out what you can add to the problem I think, or choose the part that is odd or even function? Maybe? This is a kinda confusing question

Answer 10

If it is saying what is an odd fuction you are looking for an answer with an odd degree do you know what the degree is?

Answer 11

Is the question online?

Answer 12

its on a pre cal thing i have for school

Answer 13

Is there any way you can share the question?

Answer 14

no i dont think so

Answer 15

Okay, I don't usually give answers but since this is confusing are you okay with me telling you what I think they want for the answer?

Answer 16

Than ill explain

Answer 17

yes

Answer 18

First one 2x
Second 3x^2

Answer 19

1) I put this there because It has a degree exponent of 1 which is an odd degree, does that make sense?

Answer 20

yes

Answer 21

2) Same concept I looked at 3x^2 the degree was 2 which is an even degree which means its ab even function

Answer 22

i have another question

Answer 23

So you can always look at the degree or the exponent if its odd its going to be a odd function if it is even its an even function

Answer 24

the function y=sinx/x even or odd and is y=cosx/x even or odd

Answer 25

Let me get my calculator

Answer 26

Okay an even function has same end behavior so the function will look the same at its endpoints so like x^2 both endpoints are going up in the same direction in sin(x)/x the endpoints are about the same and they are going the same way so its even, does the make sense?

Answer 27

yes

Answer 28

And now if you type in the other function do you get same endpoint behavior?

Answer 29

Or you can think does the graph look the same if you fold the y axis

Answer 30

On both sides

Answer 31

Answer 32

f(x)= - 4 is without x ?
