Question

Graph the relation. Is the relation a function? Why or why not?

Answer 1

Answer:

No; a domain value has two range values.

Step-by-step explanation:

Because domain value is the x value and range value is the y value. If the x value repeats then it is not a function.

Answer 2

Answer: I think the answer is letter A . "No; a domain value has two range values".

The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6.... The range of the function is the set of all values that f takes.

Since  

x  =  − 1

produces  

y =  9

and  

y =  4 , the relation  

( − 1 , 9 ) ,     ( 0 ,  − 1 ) ,     ( − 1 ,  4 ) ,     ( 4 ,  9 )

is not a function.

The relation is not a function.

Graph.

{ ( − 1 ,  9 ) ,     ( 0 ,  − 1 ) ,     ( − 1 ,  4 ) ,     ( 4 ,  9 ) }

Step-by-step explanation: It's either A or D

what is domain value

The value of a domain name is the price any person/entity/organization has to pay in order to purchase a name for their website. The costs can range from a one-digit number to 6- or 7-digit numbers, depending on the valuation factors. Your domain could be the name of the next big start-up or brand.... The domain of a function f(x) is the set of all values for which the function is defined

The domain is the set of all the values of  

x

. The range is the set of all the values of  

y

.

Domain:

{ − 1 ,  0 ,  4 }

Range:

{ 9 ,  − 1 ,  4 }

Remove parentheses.

{ ( − 1 ,  9 ) ,     ( 0 ,  − 1 ) ,     ( − 1 ,  4 ) ,     ( 4 ,  9 ) }

Find the inverse.

No inverse can be found
