The graph of a quadratic function has a domain of (-infinity , infinity) and range of [4, infinity). in two or more complete sentences explain how the given range of the function can you to determine whether the graph open up or down

The graph opens up because the minimum value of the function is 4 and the function goes to infinity as x -> -∞, and as x -> +∞.

Explanation:
The given domain of x = (-∞, ∞).
 Because the range of y = (4, ∞), there is a vertex at a value of (x, 4).

The function is of the form
y = a(x-h)² + 4
where
(h,4) is the vertex, for some value of x = h.
a is positive because the curve opens up.

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
