Answer:
Function.
Step-by-step explanation:
A relation is a function every x that in your domain only gets assigned to exactly one number in your range.
Basically if you have a set of points and you see that the same x is being used more than once, then it isn't a function (unless for some reason they repeated the same point).
So the x's I see in the order that your points are is 3,1,-1,-2. All of these x's are different so it is a function.
Is this multiple choice if so what are the options <span />
For part a,y < x y > -2xPoint B: (3,1) plugin x=3, y=1 y < x 1 < 3which is true, so point B satisfies the first inequality.
Not sure... about part C though sorry...
I'm assuming the first time you said "July" you meant June. If he continues his rate of 1.10 every day in the month of July he will have a total of 110.00. That would be 55+55.
X=-1/3 y+4
y=-3x+12
hope this helps!
