The general form of an absolute value function is f (x)=a|x-h|+k. From this form, we can draw graphs. This article reviews how to draw the graphs of absolute value functions.

We can graph any absolute value equation of the form y=k|x-a|+h by thinking about function transformations (horizontal shifts, vertical shifts, reflections, and scalings).

To do this, you add or subtract a value from outside the absolute value signs, like this: y=|x|–b. If b is positive, you will be moving the graph up, if b is negative, you will be moving the graph down.

To solve absolute value equations, find x values that make the expression inside the absolute value positive or negative the constant. To graph absolute value functions, plot two lines for …

Absolute value graphs make a V shape, but why do they do that? Let's explore how to make some new and interesting types of graphs. **Unit guides are here!** Power up your classroom …

To solve absolute value equations, find x values that make the expression inside the absolute value positive or negative the constant. To graph absolute value functions, plot two lines for …

One easy way to think of absolute value is the distance it is from zero. To do that, a number line comes in handy. Watch and learn.

The graph of y=k|x| is the graph of y=|x| scaled by a factor of |k|. If k<0, it's also reflected (or "flipped") across the x-axis. In this worked example, we find the equation of an absolute value …
