Answer: D .) 17% decrease
Step-by-step explanation:
I don't know how to anwser this but i had the same question and when I anwsered d i got it correct.
All we need is to put this form in the vertex form f(x) = (ax+b)^2 + c
So we have <span>f (x)= 3x^2+12x+11 ....
Let's complete the square (if you aware of it)
</span><span>
f(x)= 3x^2+12x+11 = 3(x^2+4x)+11 = 3(x^2+4x+4-4)+11
=</span><span> 3([x^2+4x+4]-4)+11 = 3[(x+2)^2-4]+11 =3</span><span>(x+2)^2 - 12 +11 = 3</span><span><span>(x+2)^2 -1
so our form would be:

Here is a parabola with vertex of (-2,-1) and with positive </span> slope (concave up)
</span>

Answer:
9, 3
Step-by-step explanation:
To get from 27 to 21, you subtract by 6. To get from 21 to 15, you must also subtract by 6. Therefore, subtracting by 6 is the pattern. In order to get the next number in the sequence, we must subtract 6 from 15.
15 - 6 = 9
The next number is 9. To find the number after 9, we must do the same thing - subtract 6 from 9.
9 - 6 = 3
The 5th number of the sequence is 3.
