Question

What is the Domain of the function indicated by the points on the plane?

A.) {-6, -2, 5}
B.) {-4, -3, 3}
C.) {-6, 3, 5}
D.) {-4, -3, -2}

Answer 1

A.) {-6, -2, 5}

Explanation:

A function
`f` from a set
`A` to a set
`B` is a relation that assigns to each element
`x` in the set
`A` exactly one element
`y` in the set
`B`. The set
`A` is the domain (also called the set of inputs) of the function. From the figure, we can see that this set is the x-coordinate of each red point. So this set is {-6, -2, 5}
