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.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.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?

anonymous

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.
