Hello there, I just really feel like the right answer is coming up wrong when entered. f(x) is shifted up 2, so f(x)+2, and is shifted four to the left, so f(x+4)+2 and is flipped around the x-axis so -f(x+4)+2. Yet it said it was wrong when I clicked on that, and then I almost choked on my tangerine! I now have tangerine juice on my knee and my completion bar took a horrible trip in the wrong direction! It was a rough 35 seconds of my life... Um, jk, about all that, just didn't want to bore you. Hopefully you can fix it or help me understand this better though! Thanks very much! Love the website sooooo much! :)

Sincerely,
Eric Larson
