Is the relation {(1, 3), (-4,0), (3, 1), (0, 4), (2, 3)} a function? Why or why not?Yes, the range value 3 corresponds to two domain values, 1 and 2.
Yes, there is no value in the domain that corresponds to more than one value of the range.
No, there is no value in the domain that corresponds to more than one value of the range.
No, the range value 3 corresponds to two domain values, 1 and 2.

Answer 1

Answer:

Answer:

"Yes, there is no value in the domain that corresponds to more than one value of the range."

Step-by-step explanation:

Recall that for a relationship to be a function, each element of the domain should have only one associated value in the range.

So in the example given in coordinate pair form: {(1, 3), (-4,0), (3, 1), (0, 4), (2, 3)}

notice that:

the element 1 in the Domain relates to 3 in the Range,

the element -4 of the Domain relates to 0 in the Range,

the element 3 in the Domain relates to the number 1 in the Range,

the element 0 in the Domain relates to 4 in the Range,

and finally the element 2 in the Domain relates to 3 in the Range.

Each of the elements in the Domain, relate to one and only one element in the Range. The fact that one of the related values is repeated is not an obstacle for the relationship to be a function.

The correct answer therefore is:

"Yes, there is no value in the domain that corresponds to more than one value of the range."

What does the base and exponent mean in math?

Answers

base is what number is being multiplied
exponent is small number above the base

The base is the number that the exponent affects/being multiplied by.

The exponent is a tiny number on the top right of the base, which identifies how many times the base will be multiplied.

A radio station requires DJs to play 2 commercials for every 10 songs they play.What is the unit rate of songs to commercial?

Answers

The correct answer for this question is that the unit rate is 5:1. Wecan work this out by simplifying down the 2 commercials to every 10songs ration, so that 10:2 becomes 5:1. We can work this out by halvingthe original ratio to simplify it.

Jamel watched his older brother Robert lift weights. The bar alone had a mass of 20 kg. On the bar he had tow 11.4 kg weights, two 4.5 kg weights , and four 450 g weights. What mass was Robert lifting ?

Answers

all you do is add them all together...
20 + 11.4 + 11.4 + 4.5 + 4.5 + 0.45 + 0.45 + 0.45 + 0.45 = 53.6Kg
(note that 0.45 is 450g in Kg, When adding things such as weight or length you want to make sure that they are all in the same unit)

Graph of a cubic polynomial that falls to the left and rises to the right with x intercepts negative 3, negative 1, and 3 Which of the following functions best represents the graph? a f(x) = x3 + x2 − 9x − 9
b f(x) = x3 + 4x2 − x − 4
c f(x) = x3 + 3x2 − 3x − 9
d f(x) = x3 + 2x2 − 4x − 8

Answers

Answer:

Option A is correct .i.e, f(x) = x³ + x² - 9x - 9 represent the graph best.

Step-by-step explanation:

Given: x-intercepts of cubic polynomial are -3 , -1 and 2

To find the cubic polynomial, f(x)

We know the x-intercept of cubic polynomial are the zeroes of the polynomials.

So the factors of cubic polynomials we get from zeroes are ( x + 3 ) , ( x + 1 ) and ( x - 3 )

Cubic polynomial , f(x) = ( x + 3 ) ( x + 1 ) ( x - 3 )

= ( x + 3 ) ( x - 3 ) ( x + 1 )

(using identity: (a-b) (a+b) = a² - b²)

= ( x² - 9 ) ( x + 1 )

= x² ( x + 1 ) - 9 ( x + 1 )

= x³ + x² - 9x - 9

Therefore, Option A is correct .i.e, f(x) = x³ + x² - 9x - 9 represent the graph best.

The correct answer is Choice A.

If you graph the function on a graphing calculator, you will find that it matches all of the necessary parts. If falls to the left and rises to the right.

It also has zeros at -3, -1 and 3.
