Decide whether the relation defines a function.

{(-8, 2), (-8, 8), (1, 4), (6, -4), (10, 2)}

A. Function

B. Not a function

B

Step-by-step explanation:

When given an ordered pair in defining a function, we have to note that each x value pairs up with a unique y value. If there is more than 1 y-value for any x-value, this would NOT be a function.

If there is ordered pair as shown below:

(2, 7), (4, 5), (-2, 3), (2, 7)

We can think that there are two 2's and this isn't a function, but wait!

2 pairs with 7 and the next one, 2 also pairs with 7, so it is a function, eventhough it is written twice. They are the same.

Now, looking at the ordered pair given in this problem:

{(-8, 2), (-8, 8), (1, 4), (6, -4), (10, 2)}

-8 is paired with "2"

as well

-8 is paired with "8"

So, there are "2" y-values for a single value of x, -8

So, it is not a function

Correct answer is B

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

idk lol xd
