If no vertical line intersects the graph of a relation in more than one point, then the relation is a function.
ki77a [65]

If a vertical line does not connect to more than one point in a relation then that relation is a function.
Then your answer is A-True.
That is called the vertical line test. The vertical line cannot touch more than one point at the same time if it is a function. If it does touch then it is not a function.

Cheryl is buying lace for her dance costume. One foot of lace costs 3 dollars. How much does each amount cost?
NemiM [27]

Answer:

3/4 of a foot will cost $2.25.

Step-by-step explanation:

This question is solved by rule of three, due to proportions.

One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?

1 foot - 3 dollars

3/4 foot - x dollars

x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25

So

3/4 of a foot will cost $2.25.
