Best ResponseYou've already chosen the best response.2f(1x) = f(x+1) f(1x) = f((x1)) so the graph of f(x) is mirrored over the y axis and we shift 1 unit to the right to get the graph of f(1x)

Best ResponseYou've already chosen the best response.2put another way, if x = 3, then f(3) = 0 since we're told that 3 is a root so f(1x) = f(1(3)) = f(1+3) = f(4) making 4 a root of f(1x)

Best ResponseYou've already chosen the best response.0Oh I see now. So any number inside the bracket of f( ) is a root of that function?

Best ResponseYou've already chosen the best response.2`The zeros of a function y= f(x) are 3 , 0 , 2` 3 is a root of f(x) 0 is a root of f(x) 2 is a root of f(x)

Best ResponseYou've already chosen the best response.2`3 is a root of f(x)` > `f(3) = 0` `0 is a root of f(x)` > `f(0) = 0` `2 is a root of f(x)` > `f(2) = 0`
