Please help me !!!!!!

Given:

The set of pair and graphs.

To find:

The domain and range.

Solution:

We know that,

Domain is the set of x-values or input values.

Range is the set of y-values or output values.

(a)

The given set of ordered pairs is

{(-3,3),(5,5),(-3,2),(5,3)}

Here, the x-coordinates are -3, 5, -3, 5.

A set contains distinct values.

Therefore, the domain is {-3,5}.

(b)

The graph is given.

From the given graph the set of ordered pairs is

{(-2,1),(-1,0.5),(-1,3),(0,0),(0,2),(1,0.5),(1,3)(2,1)}

Here, the y-values are 1, 0.5, 3, 0, 2, 0.5, 3, 1.

Therefore, the range is {0, 0.5, 1, 2, 3}.

(c)

The graph is given.

From the given graph the set of ordered pairs is

{(-2,3),(-1,3),(0,1),(2,4)}

Here, the x-values are -2, -1,0, 2.

Therefore, the domain is {-2,-1,0,2}.

Identify a possible first step using the elimination method to solve the system and then find the solution to the system. 2x − 5

tatuchka [14]

In order to use the elimination method, we have to multiply the equation by some number, so that one of the variable has the same coefficient.

For example, multiplying the first equation by 3 and the second by 2 gives the following, equivalent system:

$\begin{cases}6x-15y=33\\6x+4y=14\end{cases}$

Now, we can subtract the two equations, and we will cancel (eliminate) the x variable:

$-19y=19 \iff y=-1$

Now that y is known, plug it into one of the equations: for example, if we use the first one we get

$2x+5 = 11 \iff 2x = 6 \iff x=3$

A _____ is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.

Hatshy [7]

A <em>function </em>is a rule that assigns each vale of the independent variable to exactly one vale of the dependent variable.

The missing word is the function.

Point to remember:

The definition says that two values of x(independent variable ) may correspond to one value of y(dependent variable) but the vice versa is not true( means two values of y(dependent variable ) does not correspond to one value of x(independent variable) ). This explanation is very powerful tool to check that whether a relation is a function or not.
