Best ResponseYou've already chosen the best response.0as evidenced by the coordinates of (4,0) (0,4) (4,0)? how to get those points mathematically? y=x4, y=x+4? Or  what did you apply to get those coordinates?

Best ResponseYou've already chosen the best response.0Mathematica generated the plot with the following Plot function call: Plot[Abs[x]  4, {x, 5, 5}, AspectRatio > Automatic] The absolute value of a signed number is the number with the sign of it stripped off. For positive numbers there is no change. The absolute value of 4 is 4. 4  4 is 4  4 = 0. This is the point on the negative x axis. Remember that there is a formula to calculate y given a value of x. That is, y = x4. At x = 4 the line crosses the negative x axis because the associated y value is 4 4 = 4 4 which is 0.. When x is 0 the (0  4) = 4. Both lines meet at the point (0,4) If you did not have to contend with the absolute operator, then the line would be straight and would not change direction at (0,4).

Best ResponseYou've already chosen the best response.0One thing I forget to stress is that in evaluating a math expression with absolute values it is probably a good idea to evaluate the absolute values first changing any negative signs inside the two vertical bars to plus, at least in your mind.
