Which graph represents a function?

B

Step-by-step explanation:

a function happens when there is exactly one output given for every input

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
