Answer 1

This question again.... @justus

Answer 2

Alright so right off the bat A is eliminated

Answer 3

Ya

Answer 4

Hmm

Answer 5

Can we come back to this question later

Answer 6

Ya.

Answer 7

Organize the following expressions from greatest to least by number of terms:


I.x + 2xyz
II. 9x2yz
III.18x2 + 5ab − 6y
IV. 4x3 + 3x2 − x − 4

III, IV, I, II
IV, I, II, III
IV, III, I, II
III, II, IV, I

Answer 8

Expression I
x+2xyz is 2 terms

Expression II
9x^{2} yz is 1 term

Expression III
18x^{2}+5ab-6y is 3 terms

Expression IV
4x^{3}+3x^{2}-x-4 is 4 terms

Answer 9

IV, III,I,II

Answer 10

is this right??
Organize the following polynomial expressions from least to greatest based on their degree:


I. x + 2xyz
II. 9x3y2
III. 18x2 + 5ab − 6y
IV. 4x4 + 3x2 − x − 4
III, I, IV, II <--- This one!
IV, I, II, III
III, II, IV, I
IV, III, I, II

Answer 11

Yes

Answer 12

YESSSSSSSSS okey. Um..okey 1 min

Answer 13

Alright

Answer 14

wait for the last one that u did....i dont get it...howw....how is that the answer??

Answer 15

Its about the degrees right???

Answer 16

No its about the terms

Answer 17

You count how many terms there are in each expression

Answer 18

And then put it from greatest to least

Answer 19

Oh....so I have been doing it wrong for a while :(

Answer 20

That might explain my C

Answer 21

Oh its okay now you know

Answer 22

No.. everyone makes mistakes its okay

Answer 23

And math is pretty tricky it takes practices and there's a ton of rules

Answer 24

Organize the following polynomial expressions from least to greatest based on their degree:


I. x + 2xyz
II. 9x3y2
III. 18x2 + 5ab − 6y
IV. 4x4 + 3x2 − x − 4

III, I, IV, II
IV, I, II, III
III, II, IV, I
IV, III, I, II

So is the first option correct?? :\ or no?

Answer 25

wait ya this one says based on "degree"!!

Answer 26

Yes I believe so

Answer 27

:O OOOOOOOOOOHHHHHHHH

Answer 28

Answer 77

For the confusing one,

\(\color{#0cbb34}{\text{Originally Posted by}}\) @justus
Might be D
\(\color{#0cbb34}{\text{End of Quote}}\)
Perfect job @justus, it's D. Fractional powers cannot be considered as polynomials because it adds a restriction to the domain.

A and B are the same thing. A variable raised to the negative power is the same as a variable in the denominator.

\(x^{-n}=\frac{1}{x^n}\)

And in the problem, there was no variable in the denominator.

Answer 78

General hierarchy of relations:

-To be a relation, you just need any set of values of x corresponding to y, or vica versa.
-To be a function, you must fulfill the requirements of a relation + have a dedicated x value for any y value. X values cannot repeat
-To be a polynomial, you must fullfill the requirements of a function + have no domain restrictions (no variables in denominator, no fractional degrees)
-To be an injection, you must fullfill the requirements of a function + have the inverse of the relation be a function.

polynomials and injections are independent.

Thank you justjm.
