Answer:
(-∞, -6] U [-2, ∞)
Step-by-step explanation:
To solve this, begin by factoring this quadratic equation into its factored form:
x² + 8x + 12 ≥ 0 becomes (x+6)(x+2) ≥ 0.
x = -6, and x = -2 are the zeros of this parabola. Therefore:
(-∞, -6] U [-2, ∞) are the parts of the graph above y = 0 because the graph
opens upward.
** Remember, when the '≥' sign is present, the
square brackets must be used.
Capacity is the maximum amount that something can contain
fluid ounces is how much something contains in ounces.
