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}.

<u>Trigonometric Ratios </u>
The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios: sine, cosine, tangent, cosecant, secant, and cotangent.
The longest side of the right triangle is called the hypotenuse and the other two sides are the legs.
Choosing any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
The image shows a right triangle where the angle of 45° has x as the opposite leg, 6 as the adjacent leg, and y as the hypotenuse. The trigonometric ratio that applies here is the cosine ratio, defined as:
Solving for y:
Substituting:
Now use the tangent ratio:
Solving for x:
Substituting:
