Answer:
(2,3),(4,3),(-2,-3),(-4,-3)
Step-by-step explanation:
A function is defined as a relation in which each domain element (x-value) is paired with exactly one range element (y-value).
This means that each value we input for x must have only one possible output. If the same x-value yields more than one y-value, it is not a function.
The correct answer, as shown above, meets the criteria of a function, as each x-value is shown to produce exactly one y-value. In this set of ordered pairs, if x = 2, then y = 3, and if x = -2, then x = -3.
A set of ordered pairs is not a function if there are ordered pairs with the same x-values but different y-values.
In the other sets of ordered pairs, one x-value has more than one possible y-value. Let's use the last set as an example:
(5,1),(5,2),(5,3),(5,4)
Inputting 5 as x produces four different y values; there is no one y value for the x-value. y could equal 1, 2, 3, or 4.
Answer:
7:52am
Step-by-step explanation:
John leaves by 5:00am
He gets to school after 35 minutes
The time now is 5:00 + 0:35 = 5:35am
After 2 hours and 2 mins of lectures, the time is 5:35 + 2:02 = 7:37am
After 15 minutes, the time is 7:37 + 0:15 = 7:52am
Therefore the answer is 7:52am.
