Which of the sets of ordered pairs represents a function? (4 points) A = {(−4, 5), (1, −1), (2, −2), (2, 3)} B = {(2, 2), (3, −2

A function will not have any repeating x values....it can have repeating y values, just not the x ones
(-4,5),(-1,1),(2,-2),(2,3)
this is not a function because it has 2 sets of points that has x as 2...so it has repeating x values
(2,2),(3,-2),(9,3),(9,-3)
this is not a function because it has 2 sets of points that has an x value of 9...so it also has repeating x values
so both of these are not functions.....neither of them
Funny, this looks like a complex graph, until you realize that the numerator can be written like (x+3)(x-9).
So really, this is a straight line f(x) = x-9.
But wait, there's a catch. x≠3, because that would divide by zero. So in your straight line, you have to draw a "hole" at (3,6)
-68x + p = qx + 34
p - 34 = qx + 68x <em>added 68x to both sides & subtracted 34 from both sides.</em>
p - 34 = x(q + 68)
![\frac{p - 34}{q + 68} = x](https://tex.z-dn.net/?f=%5Cfrac%7Bp%20-%2034%7D%7Bq%20%2B%2068%7D%20%3D%20x)
The denominator cannot be equal to zero so q + 68 ≠ 0 ⇒ q ≠ -68
You didn't upload the options but look for the one that has q = -68.
I dont know if this is right BUT
X-15=5(3q-10)-5q
X-15=15q-50-5q
X-15=10q-50
+15 +15
X=10q-35
Y = 197
197 ÷ 13 = 15 and a remainder of 2
