1) Determine if the given points form the vertices of a right triangle. (-3, 5), (-1, 3), and (-4, 0).

• No

2) Identify the domain and range of the relation, and determine whether the relation is a function. {(-7, -12), (-3, -5), (1, 16), (8, 18)}

• I got the domain as {-7,-3,1,8} and range as: {-12,-5,16,18}. I think it's a function.

3) Determine if the function is odd, even, or neither. f (x) = x^3/|x+5|

• I have no clue where to even start with this one

4) Find the zeros of the function and state the multiplicities. f (x) = [x - (4 - 7)][x - (4 + 7)]

• Same with this one.

My midterm is tomorrow and I have no idea what I'm doing. Help.
