Answer:
The relation is a function!
Your Domain should be...
{-1, 1, 7, 9}
Your Range should be...
{-1, 8, 9}
WHY?
Your domain is always your x-coordinates, which are the first coordinates in a pair.
Your range is always your y-coordinates, which are the second coordinates in a pair.
When listing the points, it's important to remain a relation CANNOT be a function if the x's repeat, so luckily, they do not repeat.
Also, when listing points for your range, remember, if they repeat, you should only count one of the numbers, as you can see from the answer, there was two nines, but instead I put one.
46
When it says f(4) that means x=4
So you then just fill in all the x’s with 4’s and solve as normal
The y-intercept is where on the graph the line is intersecting the y=axis. Slope is in the form y=mx+b (b=y-intercept, mx=how far up and over.)
