Question

Which set represents the domain of the function shown? (5 points)

{(−3, 6), (0, 2), (4, 7), (11, 15)}


{(6, −3), (2, 0), (7, 4), (15, 11)}

{2, 6, 7, 15}

{−3, 0, 4, 11}

Answer 1

To make it simple, when finding the domain all you have to do is look for the x within the points.

Looking at the first set you can tell that the domain is -3, 0, 4, and 11

The y or the f(x) would be 6, 2, 7, and 15

(Just saying y and f(x) are the same thing.)

For the next set the domain is 6, 2, 7, and 15

For the f(x) it is -3, 0, 4, and 11

Remeber x and Domain is the same thing so all you have to do is look for the x within the points of the plot, as for looking for the range, it is the same thing as y or f(x).

Hope that this helps!!!!!!!!!!!!!!
