determine whether this relation is a function, state its domain and range, is it continuous or discrete.
{(-3,0), (-1,1), (0,1), (4,5), (0,6)}
Answered by oobleck
if any two pairs have the same 1st element, it is not a function
domain is the set of 1st elements, range, of the 2nd
continuous if defined over an interval, otherwise discrete.

so, whaddaya think?

is a function?
Answered by oobleck
No. two pairs start with zero.
f(0) cannot be both 1 and 6.
stop guessing.

how do i get the domain and range
Answered by oobleck - grr
1st step - read what I wrote above.
I assume you can tell which number in each pair is the 1st or 2nd.
Take a look at your text - I'm sure it explains it
try google "relation domain" or something
