Graphs are difficult to describe here but let's try. If x is 1, then y is 0. Start with point (1,0). If x is 2 then y is one. (2,1). There is a line starting at 1,0 and going up and to the right with a slope of one.
But, if x is 2, y could also be -1 because the absolute value of -1 is 1. There is another line starting at 1,0 and going down and to the right with a slope of -1.
Then, if x is -1, y is also zero. Start again with point (-1, 0). Without showing a lot of detail, the left side of the graph is a mirror image of the right side. When you are done your graph should look at bit like > < .
It has an absolute minimum at the point (2,3). It has no maximum but the ends of the graph both approach infinity.
-5
And stop cheating
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".
The absolute value of -15 is 15. (any number in absolute value is positive.)
It has an absolute minimum at the point (2,3). It has no maximum but the ends of the graph both approach infinity.
That is a result of an absolute value equation. So an Absolute Value Graph
y = |x| - 2
zero. The absolute value of a number is just the positive version of that number, so the absolute value of x is x, and x minus x is zero.
No.

Zero. The absolute value |n| is positive for any real number. Subtracting it from itself is zero.
