Find the absolute value vertex. In this case, the vertex for y=|x−5|y=|x-5| is (5,0)(5,0).
(5,0)(5,0)
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
(−∞,∞)(-∞,∞)
{x|x∈R}{x|x∈ℝ}
For each xx value, there is one yy value. Select few xx values from the domain. It would be more useful to select the values so that they are around the xx value of the absolute valuevertex.
You use Pythagoras theorem for this: You add 52 and 20 for AC which is 72 So you do X^2 = 72^2 + 30^2 X^2 =5184 + 900 X^2= 6084 X = 6084 squared root X= 78
