Answer:
a. The function is increasing for all real values of x where x < –4.
Step-by-step explanation:
Let me help you, I have answered this question once in Brainly as well
Given the factored form of the function:
f(x) = -(x + 6)(x+2)
<=> f(x) =
We will convert to vertex form
Let analyse other possible answers:
<u>a. The function is increasing for all real values of x where x < –4.</u>
True, because the parameter a = - 1 so the graph open down all over its domain
<u>b. The function is increasing for all real values of x where –6 < x < –2.</u>
Wrong, the function decrease in the interval from –4.< x < -2
<u>c. The function is decreasing for all real values of x where x < –6 and where x > –2.</u>
Wrong, the function increase in the interval from -6 < x < -4
<u>d. The function is decreasing for all real values of x where x < –4.</u>
Wrong, The function is increasing for all real values of x where x < –4.

Hi! Basically, the problem is asking us to find the values of a, b, and c in the equation 
. Since we have three unknowns, we just need three equations. We can find these equations by using the data in the table.
First let's plug x = 0 and f(x) = 0.
Now that we know c, it's time to pick two more pairs. Let's plug-in (2,78) and (4,152)
Before proceeding with the process of eliminating one variable, let us first reduce both equations to their lowest terms. We divide the first equation by 2 and we divide the second one by 4.
Next, we subtract equation 2 from equation 1.
Finally, we substitute the value of a to equation 2 to get the value of b.
Therefore, the function should be
