Answer:

First one

Step-by-step explanation:

First one, because one x-value can't have two y-values.

A function always outputs one y-value. But it can have two x-values for one y-value.

Hope this cleared things up for you!

This is a full assignment I’m struggling on if someone can answer them all and get most correct I will give you Brainliest for y

Effectus [21]

Answer:

Step-by-step explanation:

a) 1) Polynomial is closed under addition. In polynomial addition, only the coefficient change and variables and it powers does not change.

Example: Add 3x² - 2x + 7 and -2x² - 5x + 3

3x² - 2x + 7 - 2x² - 5x + 3 = 3x² -2x² - 2x - 5x + 7 + 3

= x² - 7x + 10

2)Polynomial is closed under addition. In polynomial subtraction, only the coefficient change and variables and it powers does not change.

Example: Subtract 3x - 2 from 4x + 2

4x + 2 - (3x - 2) = 4x + 2 - 3x + 2 = 7x + 4

3) Polynomial is closed under multiplication. In this, exponents of the variables are added according to the exponent rule. As the exponent of polynomials are whole numbers and whole numbers are closed under addition, the result will be a whole number.

-2x³ * 3x² = $-3*x^{3+2}=-3x^{5}$

4) Polynomial is not closed under multiplication. In division, we may get a negative exponent. So, it is not closed under division.

$\dfrac{x^{4}}{x^{9}}=x^{4-9}=x^{-5}\\\\x^{-5} \ is \ not \ a \ polynomial.$

Probability On a nearby pond, black and white ducks are swimming in groups of three. Use the table to find the experimental prob

miv72 [106K]

Answer:

There are only two choices, a black or white duck, so a coin is the best choice. To represent a set of possible outcomes, toss the coin three times. Repeat the experiment multiple times. To find the probability, divide the observed desired outcomes by the total number of trial
