Can you give graphs which are that of functions? if yes, give three graphs.

What is function?

•Given a relation in x and y, we say y is a function of x if for each element x in the domain, there is exactly one value of y in the range.  It is a rule of correspondence between two nonempty sets, such that, to each element of the first is called domain, there correspondents one and only one element of the second is called range.

To determine whether it is function or not by using the vertical line test. If the graph passed to Vertical line test it is consider as function. The graph of function defines y as a function of x if no vertical line intersects the graph in more than one point.

Here are the example of function and not function

1. The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates for example ( -1, 2), ( 1, 0), (2, 1) .

2. The second example is not a function, because it contains the ordered pairs (1,2) (1,4)( 2, -1). the first set is repeated . These have the same first coordinate and different second coordinates. Read the details about the set of ordered pairs in

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. The range is the resulting y-values we get after substituting all the possible x-values. Read the details about the definition of range in

they can be simplified through division

step-by-step explanation:

q: what happens to the common factors in the numerator and the denominator?

in fractions, if there are common factors in the numerator and the denominator, they can be simplified through division. since the factors in the numerator and denominator are equal, they would be equivalent to 1 and can be 'cancelled'.

obseve the example below:

the numerator has a value of 9 and the denominator has a value of 81.

numerator: the numerator has a gcf of 3, and can be expressed through the following:

9 = 3 * 3 =

denominator: the denominator has a gcf of 3 as well, and can be expressed through the following:

81 = 9 * 9 = 3 * 3 * 3 * 3 =

combining the values of the numerator and denomintor into one equation, we can write it as:

= =

we can cancel 9 from both numerator and denominator. doing so would yield the following value:

code: 8.3.1.2.1.
