The general equation for an absolute value function can be represented by `y = a|x - h| + k`  where "a" represents strectch/compression, (h, k) represents vertex of absolute value function.

Therefore an absolute value equation with y-intercept (0, -1) could be represented by the equation:  `y = |x| - 1.`

An absolute value function with range of `[-4,oo).`

If I place the absolute value function with vertex of (-4, 0) and positive, using the same general equation, this would yield:

`y = |x| - 4` .
