To find if one is a function, you must see if the pattern is the same.
Domains (x) can not have two values
I forget what the y value is called, but there can be the same y- value for multiple      x - values

A. is not a function, because its ordered pairs are all over the place, and the value 4 in the x - value has two values assigned - 0 and 3, which makes it invalid.

B. may be a linear function. Its ordered pairs aren't jumping all over the place.
Both the x and y go up one for one, so the function could be y = x + 3

C. isn't because the x - value 2 has two values. Again, that makes this invalid.

D.  is invalid because there is two x - values for 2. 

Therefore, the answer is B.

What is a function ? Example
salantis [7]

Answer:

We could define a function where the domain X is again the set of people but the codomain is a set of numbers. For example, let the codomain Y be the set of whole numbers and define the function c so that for any person x, the function output c(x) is the number of children of the person x.

Triangles A B C and R M Q are shown. Angles C A B and M R Q are 29 degrees. Angles A B C and R M Q are 116 degrees. What additio
Svetlanka [38]

Answer:

Therefore, the two options for triangles to be congruent using AAS are

1. BC ≅ MQ       (Additional information)

2. AC ≅ RQ       (Additional information)

Step-by-step explanation:

Given:

∠CAB =∠MRQ = 29°

∠ABC = ∠RMQ = 116°

To Prove:

Δ ABC ≅ ΔRMQ  by AAS congruence test which additional information is required

Proof:

<u>Case 1.</u>

In  Δ ABC and Δ RMQ

∠CAB =∠MRQ = 29°      ……….{Given}

∠ABC = ∠RMQ = 116°     ..……..{Given}

BC ≅ MQ                        ……….{Additional information required}

Δ ABC ≅ Δ RMQ ….{By Angle-Angle-Side congruence test}

<u>Case 2.</u>

In  Δ ABC and Δ RMQ

∠CAB =∠MRQ = 29°      ……….{Given}

∠ABC = ∠RMQ = 116°     ..……..{Given}

AC ≅ RQ                        ……….{Additional information required}

Δ ABC ≅ Δ RMQ ….{By Angle-Angle-Side congruence test}

Therefore, the two options for triangles to be congruent using AAS are

1. BC ≅ MQ       (Additional information)

2. AC ≅ RQ       (Additional information)
