Algebra 2H Unit 4 Day 5 - Applying the (h,k) format to any function

Not my video, but it's really quite good. One note - the last example that is in the video could be either a=radical 2 (so the new function is radical 2 times the original function, square root of x) or b=2 (new function is square root of 2 times x). One stretches the function vertically by radical 2, the other horizontally compresses the function by 2. These result in the same thing, since radical 2 times radical X is the same as radical 2X.
