Answer:
Yes it is a function
Step-by-step explanation:
We have to check the ordered pairs to find out if given relation is a function or not.
In an ordered pair, the first element represents the input and the second element represents the output.
The set of inputs is domain and output is range.
For a relation to be function, there should be no repetition in domain i.e there should be unique pairs of input and output.
In the given relation, the domain is {3,5,-1,-2}.
No element is repeated hence it is a function ..
Answer:
No.
Step-by-step explanation:
If they do intersect, the measurement of the angles they form is a half the difference of the intercepted arcs; both of the intercepted arcs would measure 180 degrees.

A. Always because imagine a line where one is y=x and the other is y=-x+1. The point of intersection would be (1,1)
