Question 854649
when x = 0, h(x) = 0
when x = 1, h(x) = 2
when x = -1, h(x) = 2
when x = 2, h(x) = 4
when x = -2, h(x) = 4


h(x) will always be positive.
the v shaped graph has a minimum point at x = 0.
the points on the graph are that y will always be equal to |2 * x|.
whether the expression within the absolute value signs was -2x or 2x is irrelevant.
the result will always be positive.
the domain is all real values of x.
the range is all real values of x >= 0.
the graph of |-2x| is shown below:
{{{graph(600,600,-5,5,-10,10,abs(-2x))}}}
the graph of |2x| is shown below:
{{{graph(600,600,-5,5,-10,10,abs(2x))}}}
as you can see, both graph are identical.
