On the Cartesian (x-y) plane, draw two 45-degree lines from the origin
opening to the right. One slopes up, the other slopes down.
|y| < x is the equation of the region between the two 45-degree lines,
but not including points that are on the lines.
To find an absolute value equation from a graph, first identify the vertex of the graph, which represents the point where the absolute value function changes direction. Then, determine the slope of the lines on either side of the vertex to find the coefficients. The general form of the absolute value equation is ( y = a |x - h| + k ), where ((h, k)) is the vertex and (a) indicates the steepness and direction of the graph. Finally, use additional points on the graph to solve for (a) if needed.
the graph of y = |x| (absolute value of x) looks like a V with the point of the V at the origin. When x is negative (left half of graph), the line y = -x coincides with |x| so this half has a slope of -1. When x is positive (right half of graph), the line y = x coincides with |x| so this half has a slope of +1.
The absolute value of the slope of a line represents its steepness; a smaller absolute value indicates a less steep line. As the absolute value of the slope approaches zero, the line becomes closer to horizontal. Therefore, when the absolute value of the slope decreases, the graph of the line gets flatter, indicating that the change in the y-coordinate relative to the x-coordinate is diminishing.
It depents from the value of x.If x>0 then, |x|=xIf x
The absolute value of a function changes the original function by ensuring that any negative y values will in essence be positive. For instance, the function y = absolute value (x) will yield the value +1 when x equals -1. Graphically, this function will look like a "V".

If a number is not less than zero then that is its absolute value. If a number is less than zero, its negative is its absolute value. So, if |x| denotes the absolute value of x, then |x| = -x for x<0 [since if x<0 then -x>0] and |x| = x for x>= 0
Neither statement is true. The graph of the absolute value of a function which is always non-negative will be the same as that of the original function and this need not open in any direction. Also, the graph of y = abs[x*(x-1)*(x+2)] is not symmetrical so there is no coefficient which will determine a line of symmetry.
y = |x| - 2

Go to the Wolfram Alpha site and type the following in the input box: |x|
use a line graph. Place a solid dot at 4. Shade the entire region to the left of 4.x is Less than shade Left.* * * * * The above answer is so very wrong - it has missed out the key word "absolute".Use a line graph. Put a solid dot at -4 and another solid dot at +4 and join them. Every point on the line (including the two end points) is the graph.
The absolute value of the opposite of x is x. The absolute value is the number's distance from zero on a number line. Distance can not be negative, so basically, to find the absolute value of a number you just need to make it positive. The opposite of x is -x. |-x|=x - you make the x positive Of course, if x, to begin with, represents a negative (less than zero) number than the absolute value would be -x. For example if x=-3, the opposite value of x would be 3 and the absolute value of x would also be 3 which happens to be -x.
To graph absolute value functions on your Casio fx-9750GII, first, press the "MODE" button and select "Graph" mode. Then, input the absolute value function using the notation "abs(x)" or by using the "SHIFT" key followed by the "x" key to access the absolute value function. After entering your equation (e.g., y = abs(x - 2)), press the "EXE" button and then the "F1" key to graph it. You can adjust the viewing window if needed by pressing the "VIEW" button.
No. The absolute value of any number is the non-negative value of that number.So, the absolute value of a number X, which is greater than or equal to 0, is X.The absolute value of a number X, which is less than 0, is -X.Note that, in the second case, X < 0 implies that -X > 0.
