Find the domain of the relation {(–2, 3), (–1, 3), (–1, 5)}. Then determine whether the relation is a function.

The domain is (-2,-1,) This relation is not a function because there are repeating x-values.

Step-by-step explanation:

The domain are the list of x values and x values are the first number in a given point. Ex: (0,9) x-value is 0

The domains are {-2, -1}

The relation is not a function.

pi x^2

step-by-step explanation:

pi times x squared

answer: the best estimate of the mean of the population = 14.

step-by-step explanation:

given: sheri surveyed eighty students, then generated three random samples of twenty-five student responses.

the sample mean=

⇒ the sample mean=

hence, the best estimate of the mean of the population = 14.
