Use the domain and range of each of the following relations to determine which is a function.

Setler79 [48]

Answer:

A) Not a function

B) Function

C) Function

D) Not a function

Step-by-step explanation:

If the relation has two of the same x-values (that equal different y-values), it is not a function. In other words, if each input value leads to only one output value, classify the relation as a function.

{(-4,3), (-2,-1), (-4,8)} = Not a function

{-4, 3), (-2.-1), (-7, 8)} = Function

{-4,-2,-7, 7} = Function (I think?)

{-4,3). (-2, -1). (-2, -8), (-7,8)}= Not a function

In 2010, the average price of gasoline in the U.S. was $3.06 per gallon with a standard deviation price per gallon at $0.06 per

Use Chebyshev's Theorem to 88.89 % the percentage of gasoline stations that had prices within 3 standard deviation of the mean.

What is the Chebyshev's theorem?

Chebyshev's Theorem estimates the minimum proportion of observations that fall within a specified number of standard deviations from the mean.
This theorem applies to a broad range of probability distributions.
Chebyshev's Theorem is also known as Chebyshev's Inequality.

By Chebyshev's inequality, for any distribution at least

$(1 -\frac{1}{k^{2} } )$ * 100 percentage of values falls within k standard deviation about mean .
