So what exactly is a correspondence? well, this is just a set of ordered pairs, x and y.
00:06
So in this set, i have four different ordered pairs.
00:09
So first, let's find the domain.
00:12
What exactly is the definition of domain? well, domain is just my x values or all my inputs.
00:17
So what would be all my inputs? well, my inputs, remember this is x, y, x, y are all the ordered pairs.
00:27
So my x values are going to be 9, negative 6, 7, 7.
00:30
So 9 comma negative 6, 7.
00:34
Instead of a second 7, i don't need to include in my domain.
00:39
What is my range? range is just my y values or my output.
00:43
So what are my outputs? my y values? this will be negative 2, 6, negative 6 is different than positive 6 and 8...
