a)y=3abs(x) - 3 times as vertically stretched
b)y=1/2abs(x) - 1/2 as vertically compressed
*the "A" value is what is affecting the vertical compression and stretching*
c)y=abs(3x) - 3 times as horizontally compressed
d)y=abs(1/2x) - 1/2 as horizontally stretched
*the "B" value (inside brackets) affects the horizontal compression and stretching*
Summary:
The hardest part to remember is whether it is horizontal or vertical, and today I learned which terminology to use in that certain circumstance. the absolute value refers to the value inside the brackets always being a positive value. This class was mostly a refresher, and it was useful to learn the terminology.
