Answer:

Correct answer is the domain.

Step-by-step explanation:

A domain is the input set of a function.

A range is the output set of the function.

It is more  important to know the domain of the function to be able to determine the corresponding output set so the function can be graphed. To start with the domain is very useful because every domain element has a corresponding unique output element.

Suppose you started with the range element of 9. The input set for an output of 9 is {-3,3}. This makes it hard to match up the elements. This example highlights why it is important to start with the domain rather than the range.

Find the area of the triangle given below.
Nimfa-mama [501]

<u>Given:</u>

A triangle with a base length of 22 ft and a height of 20 ft.

<u>To find:</u>

The area of the given triangle.

<u>Solution:</u>

The area of a triangle is obtained by multiplying \frac{1}{2} with its base length and its height.

The area of a triangle = \frac{1}{2} (b)(h).

The height is the distance from the base to the highest point on the triangle and the length of the base is the base length.

The given triangle has a base length of 22 ft and a height of 20 ft.

The area of the triangle = \frac{1}{2} (b)(h) = \frac{1}{2} (22)(20).

\frac{1}{2} (22)(20) = \frac{1}{2} (440) = 220 ft².

The given triangle has an area of 220 ft².
