<h3>When a relationship represents a function?</h3>
A relationship represents a function when each input is mapped to only one output.
In this problem:
- For the Venn sets, only one line departs each value of x, hence it is a function.
- For the ordered pairs, each value of x(2, 5 and -4), is mapped to only one value of y, hence it is a function.
- The graph has no vertically aligned points, hence it is a function.
Thus all the options are correct.

Answer : Sheeeeeeesh this is tuff I don’t know
Answer:
Step-by-step explanation:
Set this up as a ratio of number of cakes to cups of sugar, C:S
Then the ratio given is 1:2.5 which says 1 cake takes 2.5 cups of sugar. We want to know how many cakes, x, will be made with 37.75 ups of flour:
and cross multiply to solve:
2.5x = 37.75 so
x = 15.1 cakes or just 15 cakes (cuz you can't make one-tenth of a cake!)
