Best ResponseYou've already chosen the best response.1to shift f(x) 6 units to the left, we replace every x with x+6

Best ResponseYou've already chosen the best response.0so it would be x+6+4?

Best ResponseYou've already chosen the best response.1Correct \[\Large f(x) = 2^{x+4}\] \[\Large f(x+6) = 2^{x+6+4}\]

Best ResponseYou've already chosen the best response.1simplify x+6+4 and compare it to xk to figure out what k would be

Best ResponseYou've already chosen the best response.0wait would it be 10k?

Best ResponseYou've already chosen the best response.1\[\Large x + 10\\ \Large x  (10)\\ \Large x  (\color{red}{10})\\ \Large x  \color{red}{k} \] So k = 10

Best ResponseYou've already chosen the best response.0but there isnt a 10 as an answer

Best ResponseYou've already chosen the best response.1oh I went the wrong direction. It's to the right, so x gets replaced with x6

Best ResponseYou've already chosen the best response.1f(x) = 2^(x+4) f(x6) = 2^(x6+4) f(x6) = 2^(x2) so k = 2
