To find an equation in the form y = aabs(x-h) +k, do the following: The graph will be shaped like a V or an upside down V The vertex is the point (h, k), so look at the graph to determine the coordinates of the vertex. Views . PreCalculus: Becker Date:_ Name:_ 1.3 Absolute Value Practice 1. Sometimes numbers are positive or negative but have the same magnitude. 1. Step & Key Operation Notes (When using EL-9650/9600c) *Use either pen touch or cursor to operate. The absolute value of a number or equation, is another word for the magnitude of a value. x - 1 = 0 and y = 0. x = 1 and y = 0. So this is a function, or a graph, with an absolute value in it. We enlisted the help of algebra teacher and Instagram sensation, Rory Yakubov (@iteachalgebra), to help you graph your little hearts out. We will use the sliders to compare it to translate it in comparison to the parent function. The graph of the absolute value function for real numbers. An online graphing calculator to graph and determine the properties of functions. How do you graph absolute value equations on a coordinate plane? Return all settings to the default value and delete all data. Once you have practiced graphing several absolute value equations and understand its behavior, you can check your work using a graphing calculator or an online graphing calculator like Desmos. It is possible for the absolute value function to intersect the horizontal axis at zero, one, or two points. Parent graph: y =x y =x +2 y =x +4 y =x +8 a. No, they do not always intersect the horizontal axis. x = 2 and y = -2. Detailed Answer Key. y - h = |x - h| That is, y = -|x - 2| - 2. Absolute Value Equations Calculator is a free online tool that displays the absolute value for the given equation. If I used ax (or xa) the program just gets confused. y + 2 = -|x - 2| To get the vertex, equate (x - 2) and (y + 2) to zero. Below is the Absolute Value Function parent function. 6. a = 1. - 2-4 View the graph.
