Which set represents the domain of the function shown? {(-3, 6), (0, 2), (4,7), (11, 15)}
O-3, 0, 4, 11)
O {2,6,7, 15)
O {(6,-3), (2,0), (7,4), (15, 11)}
O {-3,0,2,4,6, 7, 11, 15)

A) {2,4,5,11}

{(2,3),(4,7),(5,9),(11,6)}

The numbers are given in ordered pairs (x,y)

First number is x  and the second number is y

x values are : 2, 4, 5, 11

y values are : 3, 7 , 9 , 6

Domains of a function are the set of x values

so for domain  we take all the x values and we write inside the brackets { }

Domain  is {2, 4, 5, 11}
