Each of the following tables defines a relationship between an input x and an output y. Which of the relationships represents functions? a. Table A and Table C

b. Table A and Table B

c. Table B and Table C

d. Table C and Table D

Please Help, Thank you.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
