What is the domain of the relation? {x| x = –4 , 0, 1, 2}. {x| x = –7, –6, 2, 3, 11}. {y| y = –4, 0, 1, 2}. {y| y = –7, –6, 2, 3
1 answer:
The domain of the relation can be expressed as: B. {x{x=-7, -6, 2, 11, 3}.
<h3>What is the Domain of a Relation?</h3>The domain of a relation can be defined as all possible set of x-values or inputs that correspond to the respective y-values or outputs of the relation. The set of y-values or output, on the other hand, make the range of the relation.
In the relation given in the image above, the domain values are the inputs (x-values) while the range values are the outputs (y-values).
The set of x-values that make up the inputs in the given relation are: -7, -6, 2, 11, and 3.
We can state that -7, -6, 2, 11, and 3 are the domain of the relation, while the range of the relation include: 0, 1, -4, and 2.
Therefore, the domain of the relation can be expressed as: B. {x{x=-7, -6, 2, 11, 3}.

Answer:
Step-by-step explanation:
The graph you see there is called a parabola. The general equation for the graph is as below
To find the equation we need to find the constants a and b. The constant b is just how much we're lifting the parabola by. Notice it's lifted by 1 on the y axis.
To find a it's a little more tricky. Let's use the graph to find a value for a by plugging in values we know. We know that b is 1 from the previous step, and we know that when x=1, y=3. Let's use that!
Awesome, we've found both values. And we can write the result.
I'll include a plotted graph with our equation just so you can verify it is indeed the same.
