Question 529595: Please help, i can't figure this out. Thank you.
Suppose that the relation H is defined as follows.
H = { (-7,-8),(3,0),(7,-8) }
give the domain and range of H, write answer using set notation.
Domain=
Range=
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
You have a set of (x, y) value pairs that relates each first number (x) to a value for the second number (y).
This represent a relation that gives you a y for each x, so it could be thought of as a function y=f(x).
We consider the set of x values {-7, 3, 7} the domain.
The set of y values that result from applying that function is the range.
