The Domain is any number that is the X value while Range is any number in Y value

In this case the domain is the first numbers in the ordered pairs-
(-3 , 2)
(0, -1)
(1, -2)
(5, 1)

Therefore the answer is A {–3, 0, 1, 5} Because all these numbers are in the X place

Answer:

{-3, 0, 1, 5}.

Step-by-step explanation:

The domain of a set of ordered pairs will be the x values of the ordered pairs in the set. So, in the graph we have the following ordered pairs:

(-3, 2), (0, -1), (1, -2), (5, 1).

Then, the domain will be the set of the x values (the first components in the ordered pairs), that is {-3, 0, 1, 5}. So, the answer is the first option.

The error percentage is 4.13%.

<h2>Error percentage</h2>

The amount of mistakes is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Given

Annie estimates that the height of a bookcase is 78.25 in.

The actual height is 75.50 in.

The error percentage.

<h3>How to find the error percentage?</h3>

We know the formula for the error percentage.

$\rm \% Error = \dfrac{Measured \ value- Actual\ value}{Actual\ value} * 100\\\\ \% Error = \dfrac{78.25 - 75.50}{78.75}*100\\\\ \% Error = \dfrac{3.25}{78.75}*100\\\\ \% Error = 0.0413*100\\\\ \% Error = 4.13 \%$
