Determine whether the relation is a function. [(-4,6),(-1,3),(3,3),(8,-9)]

• Pre Calc -

Function:
for every element in the domain (the x's) there is one and only one value in the range (the y's)
or in simpler terms
We do not want to see two or more different points with the same x value.

so what do you think?
