Question 981110
{{{ f(x) = abs( x+2 ) }}}
The absolute value can never be negative,
so {{{ f(x) }}} is always positive
---------------------------
{{{ f(x) = 0 }}} when {{{ x = -2 }}} because
{{{ abs( -2 + 2 ) = 0 }}}
--------------------
You can think of this function as 2 functions:
{{{ abs( -x + 2) }}} and
{{{ abs( x + 2 ) }}} where {{{ x }}} is always
positive
Here's the plot:
{{{ graph( 400, 400, -12, 10, -2, 10, abs( x+2 ) ) }}}
