Which of the following represents a function
Oksana_A [137]

Answer:

(2,3),(4,3),(-2,-3),(-4,-3)

Step-by-step explanation:

A function is defined as a relation in which each domain element (x-value) is paired with exactly one range element (y-value).

This means that each value we input for x must have only one possible output. If the same x-value yields more than one y-value, it is not a function.

The correct answer, as shown above, meets the criteria of a function, as each x-value is shown to produce exactly one y-value. In this set of ordered pairs, if x = 2, then y = 3, and if x = -2, then x = -3.

A set of ordered pairs is not a function if there are ordered pairs with the same x-values but different y-values.

In the other sets of ordered pairs, one x-value has more than one possible y-value. Let's use the last set as an example:

(5,1),(5,2),(5,3),(5,4)

Inputting 5 as x produces four different y values; there is no one y value for the x-value. y could equal 1, 2, 3, or 4.

Five minutes after birth, a newborn is pale; has irregular, slow respirations; has a heart rate of 120 beats/min; displays minim
Natalija [7]

Answer:

5

Step-by-step explanation:

The Apgar score is calculated based on 5 medical criteria:  

-Appearance – skin color

-Pulse – heart rate (taken with a stethoscope or by feeling the umbilical cord)

-Grimace – reflex response

-Activity – muscle tone

-Respiration – breathing quality

Each one of the criteria is evaluated on a 0 to 2 scale, once every criteria are measured, the values are added up and the child would have an Apgar score between 0 and 10.  

Here:

Apparence = 0

Pulse = 2

Grimace = 1

Activity = 1

Respiration = 1

Total= 2 + 1 + 1 + 1 = 5
