Best ResponseYou've already chosen the best response.0If (5,4) is on the graph... then the function f(x) evaluated at x=5, will give us an output of 4.

Best ResponseYou've already chosen the best response.0Hmmm what can we do with that :d Sec, trying to understand the question.

Best ResponseYou've already chosen the best response.0F(1/3x) The 1/3 will multiply our x values by 3.. Does that make sense?

Best ResponseYou've already chosen the best response.0I think so, you multiply 5 and 4 by 3?

Best ResponseYou've already chosen the best response.0so to get (5.4) in this new equation you'd need.. F(1/3x) x=15 No your y does not change only how fast or slow it takes for the graph to reach that point

Best ResponseYou've already chosen the best response.0if it was 3f(1/3x) then we would multiply our "y" 3 times and our x by 3

Best ResponseYou've already chosen the best response.0oh is that what they wanted? Hmm wording was really confusing :U

Best ResponseYou've already chosen the best response.0All I know is I'm supposed to enter an ordered pair and x is supposed to stay the same

Best ResponseYou've already chosen the best response.0Suppose, F(x) = 3x F(5) = 3(5) F(5)= 15 (5,15)

Best ResponseYou've already chosen the best response.0Now we have F(1/3x) what would be the corresponding point for the function

Best ResponseYou've already chosen the best response.0so we know when x=5 then we have 15

Best ResponseYou've already chosen the best response.0f(1/3x) = F(5) 1/3x =5 x=15

Best ResponseYou've already chosen the best response.0so on our second equation we know if x is 15 we have f(5) = y

Best ResponseYou've already chosen the best response.0its just your x changing not y

Best ResponseYou've already chosen the best response.0okay so 5 stays the same, what happens to y?

Best ResponseYou've already chosen the best response.0So we have a point (5,4)

Best ResponseYou've already chosen the best response.05,4 is the original points given, I didn't even think it was possible that the answer would literally be in the question

Best ResponseYou've already chosen the best response.0this can be rewritten as f(5)= 4 F(x) we have this new equation which is the same general shape but it has f(1/3)
