Determine if the set of points (-1,3), (2,5), (3,8), and (4,5) is a function. Explain. The set of points is not a function because the range consists of the value 5 two times.

The set of points is a function because each value in the domain corresponds to exactly one value in the range.

The set of points is not a function because each value in the domain corresponds to exactly one value in the range.

The set of points is a function because the range consists of the value five two times. ​

(a)

Step-by-step explanation:

A function is a relation between two sets that associates the distinctive components of the first set to the second set distinctive elements.

Points are

given points is not a function because each point is not associated with a unique point. for example, 2 and 4 is associated with the same number 5

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
