Question

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

Answer 1

Answer:

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

Step-by-step 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}
