Best ResponseYou've already chosen the best response.0a relationship is a function if each x value has one and only one corresponding y value

Best ResponseYou've already chosen the best response.0so which of these sets of values has only one of each x value represented?

Best ResponseYou've already chosen the best response.0Actually, you can have x value repeated, if, and only if, it has the same y value each time. However, you cannot have any x value which has more than one y value.

Best ResponseYou've already chosen the best response.0I'm not going to give you the answer. I will tell you how to find it yourself. Those numbers, I'll take letter D as an example: {(–4, 1), (–2, 3), (–1, 1), (–1, 5), (3, 2)} they come in pairs, which are (x,y). D has (4,1) (2,3) (1,1) (1,5) (3,2) so our x values are 4,2,1,1,3 respectively. Notice that 1 appears twice in the list. Does it have the same yvalue each time? If it does not, then this is a relationship but not a function.

Best ResponseYou've already chosen the best response.0Can you list all of the xvalues for the pairs given in C?

Best ResponseYou've already chosen the best response.0here is the list for C: {(–4, 1), (–2, 3), (–1, 2), (3, 5), (3, 2)} looks like the values for x are 4 2 1 3 3 agree, or disagree?

Best ResponseYou've already chosen the best response.0okay, what are the corresponding y values? in particular, what are the corresponding y values for the two x values where x is 3?

Best ResponseYou've already chosen the best response.0here are the two I'm talking about: (3,5) (3,2) same x values, but different y values. therefore, NOT a function. C is not the correct answer.

Best ResponseYou've already chosen the best response.0Ohhhhhhhhhhhhhh.......D is the correct answer????

Best ResponseYou've already chosen the best response.0I'll repeat what I said earlier about D: Those numbers, I'll take letter D as an example: {(–4, 1), (–2, 3), (–1, 1), (–1, 5), (3, 2)} they come in pairs, which are (x,y). D has (4,1) (2,3) (1,1) (1,5) (3,2) Notice how there are two pairs that have 1 as the first number? Do they have the same second number? If not, it is NOT a function.

Best ResponseYou've already chosen the best response.0Let's look at A: {(–4, 3), (–2, 3), (–1, 2), (2, 5), (3, 2)} here are the xvalues 4 2 1 2 3 are any of the xvalues the same? If not, then it is a function.
