. Graph the relation. Is the relation a function? Why or why not?
{(-1, 1), (-2, 1), (-2, 2), (0, 2)}

Yes; there is only one range value for each domain value.

No; a range value has two domain values.

No; a domain value has two range values.

Yes; there is only one domain value for each range value.

The answer is letter B "No; a range value has two domain values".

For a relationship to be a function, there must be a one-to-one correspondence between the x and y values.  For every value of x, there must be only one value for y.  So the first set is a function and the second set is not.

No; a range value has two domain values.

Step-by-step explanation:

Output has to be unique for all inputs.

Output for -2 is not unique

Step-by-step explanation: It is either B or C

Since  

x  =  − 2

produces  

y  =  1

and  

y  =  2 , the relation  

( − 1 ,  1 ) ,     ( − 2 ,  1 ) ,     ( − 2 ,  2 ) ,     ( 0 ,  2 )

is not a function.

The relation is not a function.

No; a range value has two domain values

Step-by-step explanation:

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
