Answer: No, it is not a function.

Step-by-step explanation:

  • A function is a special kind of relation between two variables commonly x and y such that each x (input) value corresponds to a unique y(output) value.

The given relation:  {(3, −2), (1, 2), (−1, −4), (−1, 2)}

According to the above definition, the given relation is not a function because -1 corresponds to two different output values i.e. -4 and 2.

Hence, the given relation is not a function.

Answer:

<h2>It's not a function.</h2>

Step-by-step explanation:

A function is a process or a relation that associates each element x of a set X, to a single element y of another set Y.

We have:

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

for x = -1 are two values of y = -4 and y = 2. Therefore this realtion is not a function.

What is the answer for -31 = 9+ 8x? Step by Step.
ryzh [129]

Answer:

<em>-5</em>

Step-by-step explanation:

-31=9+8x

we need to isolate the variable by moving 8x to the left side and -31 to the right side....therefore 8x becomes a negative, -8x, and -31 a positive....so now it would look like...

-8x=9+31

then we work the right side out...

-8x=40

to get x we need to divide -8x by 8 so we do the same to the right side as well....

-8x=40

÷8 ÷8

so...

<em>x=-5</em>

hope this helped you- have a good day bro cya)

Kendall has three jars of golf balls. One jar has a white and pink golf ball. The second jar has an orange and purple golf ball.
Mila [183]

Answer:

<h2>The total number of outcomes is 8.</h2>

Step-by-step explanation:

We know that there are different golf balls, white and pink, orange and purple, yellow and red. There are three jars with two golf balls each.

If Kendall chooses one golf ball from each jar, the total number of balls selected would be 4. Now, there are two different colors per jar, and 8 total golf balls with different colors. But, the sets can't have repetitions, and the order matters.

Having said that, the total number of possible sets is:

  • White, Orange, Yellow.
  • White, Purple, Red.
  • White, Orange Red.
  • White, Purple, Yellow.
  • Pink, Orange, Yellow.
  • Pink, Purple, Red.
  • Pink, Purple, Yellow.
  • Pink, Orange, Red.

Notice that these eight outcomes includes all possible results.

Therefore, there are 8 possible outcomes.
