Absolute Value Function Transformations
[b][size=150]The absolute value function is [color=#ff0000]y = |x|[/color] , denoted by function g. [br][br][/size][/b]The transformed basic function is [color=#ff0000][b]y = a|bx - h| +k[/b][/color].[br][br][b][color=#ff0000][size=150]Note[/size][/color][/b]: The 'slider' feature on the x-y coordinate plane can be used to change the [color=#ff0000][b]a, b, h, and k[/b][/color] values [br] for the following exercises. To do so, place the cursor and hold it on the dot of the slider and [br] slide it to the desired m and b values.[br] To move the slider to a different location on the x-y plane, place the cursor and hold it on the line [br] of the slider and move it to the desired location.[br][br][b][color=#ff00ff]Note: You can zoom in or out with the mouse.[/color][/b]
