Each set of ordered pairs represents a function. Write a rule that represents the function. 1. (0,0),(1,4),(2,16),(3,36),(4,64) 2. (0,0),(1,0.5),(2,2),(3,4.5),(4,8)

My answer to the question is as follows:

First one looks like you are squaring the number, then multiplying the result by 4, i.e.

y=4x2

second one is similar, but instead of squaring and multiplying by 4, you are squaring and then dividing by 2

I hope my answer has come to your help. God bless and have a nice day ahead!

Give 3 ordered pairs that satisfy the equation y=12x

To find ordered pairs that fit this equation, you just have to choose an x-value then record the answer for your y-value. you can literally go for anything you want, but it’s easiest to pick smaller values:

when x = 1…
y = 12(1)
y = 12
ordered pair: (1, 12)

when x = 0…
y = 12(0)
y = 0
ordered pair: (0, 0)

when x = 2…
y = 12(2)
y = 24

HELP!! Which of the following is not a possible value for a probability? A. 0.001 B. 1/16 C. 0.82 D. 5/4

Answer: Option ‘D’ is correct.

Step-by-step explanation:

Since we know that

Probability is the giving the possibility of given outcome or any certain events.

Probability is the number of ways of achieving the success.

Probability of event that certain to happen is 1.

Probability of event that is impossible is 0.

Sum of probabilities of all likelihood occurring events is 1.

So, Probability of any event can exceed 1.

But,

frac{5}{4}=1.25text{ which is greater than 1}\

Hence, it is not possible value for a probability .

Therefore, Option ‘D’ is correct.
