Domain = {2 , 4 , 8 , 1 , -5}
Explanation:
The domain of any relationship is the set of the elements of all the ordered pairs which are of the set from which the relation is laid out.
In simpler words, you just need to write the first members of all the ordered pairs.
As in this case:-
in the ordered pair (2, 0)
2 is the domain as it is the starting of the ordered pair.
Similarly, 4, 8, 1, -5 are the domains of other ordered pairs.
Option A.Domain:{4, 8, 1, -5} ; Range: {0,-2,6}
How do I find the domain and range of a function?
To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).
