Graph y=2/3*|x-1|-4

Math
y=23⋅|x-1|-4
Find the absolute value vertex. In this case, the vertex for y=2(|x-1|-6)3 is (0,2(|x-1|-6)3).

To find the x coordinate of the vertex, set the inside of the absolute value equal to 0. In this case, =0.
=0
Since there is no variable to replace, the result is 2(|x-1|-6)3.
y=2(|x-1|-6)3
The absolute value vertex is (0,2(|x-1|-6)3).
(0,2(|x-1|-6)3)
(0,2(|x-1|-6)3)
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.
Interval Notation:
(-∞,∞)
Set-Builder Notation:
{x|x∈ℝ}
For each x value, there is one y value. Select few x values from the domain. It would be more useful to select the values so that they are around the x value of the absolute value vertex.
