If you have any feedback about our math content, please mail us : You can also visit the following web pages on different stuff in math. To get the vertex, equate (x - 4) and y to zero. Before graphing any absolute value function, first we have to graph the parent function : x  =  - 3 -----> y  =  |-3|  =  3 -----> (-3, 3), x  =  - 2 -----> y  =  |-2|  =  2 -----> (-3, 3), x  =  - 1 ----->  y  =  |-1|  =  1 -----> (-3, 3), x  =  0 -----> y  =  |0|  =  0 -----> (0, 0), x  =  1 -----> y  =  |1|  =  1 -----> (1, 1), x  =  2 -----> y  =  |2|  =  2 -----> (2, 2), x  =  3 -----> y  =  |3|  =  3 -----> (3, 3). An even better version of this graph would be to include open circles at x = -4. Key vocabulary that may appear in student questions includes: translation, shift, slide, dilation, stretch, horizontal, vertical, and reflect. This not only shows the discontinuity, but also indicates that the function is undefined at x = -4.

Quick tutorial on how to use Desmos graphing calculator to graph Linear Absolute Value Functions. Graphing an absolute value function can be a bit deceiving. Prior to this lesson, my students have evaluated and written piecewise-defined functions. I think that this is an absolute value graph because x is between an absolute value sign. Watch Queue Queue. You can also use the absolute value symbol in the Desmos keyboard. Looking at the “word bank” above, what is your best guess as to what this parent function is? In this worked example, we find the equation of an absolute value function from its graph. 6. y = 2 − x. This is because x = -4 causes the denominator to be zero. Students will see this recorded in IC. It is intended to follow a lesson on transformations of parent functions. Because there is negative sign in front of the absolute sign, we have to flip the curve over. But if you were determining whether the function was continuous at x = -4, the two graphs would lead to different conclusions. This video is unavailable. 2:56. The graph consists of a horizontal section at y = -1 and another at y = 1 . 3:09 of the video shows how to graph absolute value … When we look at the above graph, clearly the vertex is, Write the given absolute value function as.
