<span>The total distance traveled and the time spent driving on the trip can be represented by both a relation and a function</span>
Answer: the answer will be none
Step-by-step explanation:
<span>In a Metro there are:
20 rows of seats
18 seats in a row
and $5 per ticket
Using commutative property of Multiplication:
Therefore.
=> (20 x 18) x 5 = 5 x (18 x 20)
=> 360 x 5 = 5 x 360
=> 1800 = 1800
Therefore, they have $1800 income.</span>
Answer: This is <u>not</u> a function
Why not?
The input x = 2 leads to more than one output. In this case, it leads to y = 20 and y = 40 simultaneously. This is the reason why we don't have a function. A function is only possible if each input x leads to exactly one y output.
Put another way: we cannot have x repeating any values if we want a function.
Side note: We could have y repeat however. So it's possible to have a function with the two points (1,5) and (3,5).
