x ≥ - 1
Step-by-step explanation:
the solid circle above - 1 on the number line indicates that x can equal - 1
the arrow points right indicating x is greater than or equal to - 1 , that is

ANSWER
EXPLANATION
The given function is:
Factor -3 for the first 2 terms.
We add and subtract the square of the coefficient of x.
Factor the perfect square trinomial.
The vertex form is:
This is very simple, all you have to do is subtract 18 and 6 and that would be 12, and now we have 12 as a POSSIBLE answer, lets check our work to be 100% correct so now try to add 12 and 6 and we get 18, so yay it made the equation true and since its true its right so that's the answer.
Answer: c = 12 so 18 = 12 + 6 is true.
