The domain is all of the x - values, while the range is all of the y - values. If there are two point with the same x - values, then it is not a function. Therefore, your answer would be A.
Hope this helped, and have a nice day!

Domain (ur x values) are {-4,-1,1,4}
range (ur y values) are {-1,1,4}..if u have repeating numbers, u only have to write them once
yes, this is a function because there are no repeating x values

What is the measure of angle c? (Brainliest and Bonus points for best answer)

k0ka [10]

Answer:

$\displaystyle 65°$

Step-by-step explanation:

Angle <em>b</em> and 135° form a <em>linear pair</em>, so when summing them up to 180°, you will have 45° left over:

$\displaystyle 180° = 135° + m∠b; 45° = m∠b$

Now, by the <em>Vertical</em><em> </em><em>Angles</em><em> </em><em>Theorem</em>, angle <em>a</em> and 70°, in this case, are to be in <u>congruence</u> with each other, so you have that.

Now you must find the the measure of angle <em>c</em> sinse you have already found the measure of two angles already:

$\displaystyle 180° = 45° + m∠c + 70° → 180° = 115° + m∠c; 65° = m∠c$

I am joyous to assist you at any time.
