Best ResponseYou've already chosen the best response.0So basically, for it to be a function, you cant have 2,6 and 2,7 because that means that the x element (2) has two different y elements.

Best ResponseYou've already chosen the best response.0For a function note these point every element of set domain must be used . every element of set domain must have only one image now guess what is the correct answer

Best ResponseYou've already chosen the best response.0a vertical line test is used to determine if we have a function or not, but then we have to plot these points manually and that might not be the best way to handle this. We usually focus on the x values. So any x value repeating itself is not a function.

Best ResponseYou've already chosen the best response.0pick the one where there is no repeat in the first number in each ordered pair for example 2 is not right because \[b. {(\color{red}2, 0), (\color{red}2, 1), (2, 2), (2, 3)} \] the 2 repeats

Best ResponseYou've already chosen the best response.0ok now that B isn't the answer . Let's look at the xvalues for a c and d a. 4 6 8 8 c. 3 4 5 5 d. 0 1 2 3 can you see which multiple choice is repeating?
