Explain how the following ordered pairs represent or doesn't represent a function - {(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)} a. for every x value there is one y value - not a function b. for every x value, there is only one y value - a function c. for every y value, there is one x value - function d. for every y value, there is one x value - not a function

The appropriate choice is ...

... b. For every x value, there is only one y value - a function

A relation that maps an x-value to only one y-value is a function.

Hey there!!

In order for something to be a function, the x values shall not repeat.

Hence, the appropriate answer would be option ( B )

Hope it helps!!

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
