Answer:

Domain: {-4, -2, 1, 2, 4}

Range: {-4, -2, -1, 1, 4}

The relation is a function.

Step-by-step explanation:

A relation is any set of ordered pairs, which can be thought of as (input, output).

A function is a relation in which no two ordered pairs have the same first component and different second components.

Remember that a function can only take on one output for each input. We cannot plug in a value and get out two values.

The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

I did the Vertical Line Test on your given graph. As you can see from the attached screenshot, each vertical line crosses the graph only once. Therefore, the given relation is a function.

The domain of the given relation is the set of x-values, while the range is the set of y-values. You'll have to list the ordered pairs in order to determine the domain and range of the given relation.

Relation: {(-4, -1), (-2, 1), (1, -2), (2, 4), (4, -4)}.

Domain: {-4, -2, 1, 2, 4}

Range: {-4, -2, -1, 1, 4}

A species of animal is discovered on an island. Suppose that the population size of the species can be modeled by the following

andriy [413]

Answer:

The initial population size is of 58.

The population size of the specie after t years is given by:

$P(t) = \frac{520}{1 + 8e^{-0.3t}$

Step-by-step explanation:

Population size of the specie:

The population size of the specie after t years is given by:

$P(t) = \frac{520}{1 + 8e^{-0.3t}$

Initial population size

This is P when $t = 0$ , that is, $P(0)$ . So

$P(0) = \frac{520}{1 + 8e^{-0.3*0} = \frac{520}{1+8} = \frac{520}{9} = 57.7$

Rounding to the nearest number, 58

The initial population size is of 58.

A rectangular room has an area of 131 1/4 square feet. The length of the room is 12 1/2 feet. What is the width, in feet, of the

Vsevolod [243]

Before we try to solve anything, let's convert our fractions into decimals, this so if we use a calculator (or writing on paper), it will be much easier to put it.
131 1/4 = 131.25 (divide 100 by the denominator to know each 1/x value).
12 1/2 = 12.50
The formula for the area of a rectangle is L x W, or Length x Width.
Since we are looking for our width, w, we need to divide by the length.
131.25 / 12.5 = 10.5.
Our width is 10 1/2 ft.
I hope this helps!

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for t

notsponge [240]

It should be noted that the expression that.can be used to describe the sequence below is an = 2 + (n - 1)

<h3>How to illustrate the information?</h3>

It should be noted that an arithmetic sequence implies that the difference between the pair are the same.

It should be noted that the common difference between the numbers is illustrated as:

= 3 - 2 = 1.

Therefore, it should be noted that the expression that can be used to describe the sequence below is an = 2 + (n - 1)
