The label on a large bag of flour states that it has 2 times as many cups of flour as a small bag. casey measures 16 cups of flour in the small bag.

which multiplication sentence shows how many cups of flour are in the large bag? (a) 2×2=4
(b) 2×8=16
(c) 2×16=32
(d) 16×16=256

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.
