Best ResponseYou've already chosen the best response.1hehehe I don't think you read the attachment that was shared to you. read it a little bit, will you? it will help you answer a lot of problems regarding functions

Best ResponseYou've already chosen the best response.1okay, you're just obviously guessing. did you read the attachment?

Best ResponseYou've already chosen the best response.0i did. but none of them look like that. or else i would have known it at first.

Best ResponseYou've already chosen the best response.1by the way, do you understand the [ ] and   in A and B respectively?

Best ResponseYou've already chosen the best response.0i understand the absolute value signs but i dont know what the bracket things are

Best ResponseYou've already chosen the best response.1brackets and curly braces are used when there are nested parentheses to avoid confusion –{2x – [3 – (4 – 3x)] + 6x}

Best ResponseYou've already chosen the best response.0so it would be B because the graph of y = x passes the vertical line test??

Best ResponseYou've already chosen the best response.1so your A is just simply x = y, which is y = x now if you read the attachment, this could mean f(x) = x

Best ResponseYou've already chosen the best response.0ok so it could mean f(x) = x?

Best ResponseYou've already chosen the best response.1yes, it means that the output is the same as the input f(x) the x inside the parenthesis, gives an output of x f(x) = x f(2) = 2 f(blah) = blah

Best ResponseYou've already chosen the best response.1will it pass the vertical or horizontal line test?

kaylalynn

Best ResponseYou've already chosen the best response.0if x = 2 or 3 or 4 etc. it will pass the vertical line test which means it is a function. But it will not pass the horizontal line test which means it is not a 1  1 function.

Best ResponseYou've already chosen the best response.0x does not pass the vertical line test so it is not a function

Best ResponseYou've already chosen the best response.0>> which is a function? @kaylalynn A function f is the set of ordered pairs (x,y) such that if (x1, y1) AND (x1,y2) are elements of f, then y1 = y2.
