Question 51186: Determine whether the relation is a function. If it is a function, state its domain and range.
{(–8, 7), (–5, –4), (–3, 3), (–3, 6)}
a. Domain: {7, –4, 3, 6}; Range: {–8, –5, –3}
b. Domain: {–8, –5, –3}; Range: {7, –4,3, 6}
c. Domain: {–8, –5, –3}; Range: 11
d. The relation is not a function.

Given: {(–8, 7), (–5, –4), (–3, 3), (–3, 6)}
First, the Domain is the set of all x values, which are the first numbers in each pair: {-8,-5,-3}.
Second, the Range is the set of all y values, which are the second numbers in each pair: {7,-4,3,6}
Third, it is NOT a function, since two points have the same x coordinate: (-3,3) and (-3,6).
Now,
a. Domain: {7, –4, 3, 6}; Range: {–8, –5, –3}
Domain and range are backwards. False
b. Domain: {–8, –5, –3}; Range: {7, –4,3, 6}
Both are correct!! True
c. Domain: {–8, –5, –3}; Range: 11
Domain is correct, but range is wrong. False
d. The relation is not a function.
This is true.
