I got -18-3r
Don't know if the last number is -3r
Answer:
Step-by-step explanation:
First, look at the graph to determine whether it opens down or up, which in this case is <em>down</em>, so you insert a negative in front of the expression. Next, locate your <em>x-intercepts</em> [<em>zeros</em> (where the graph insects the x-axis)]. You will see that the graph intersects ![\displaystyle [-2, 0]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B-2%2C%200%5D)
and ![\displaystyle [4, 0],](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B4%2C%200%5D%2C)
so what you do is insert the zeros' OPPOCITES into the equation because according to the vertex equation, ![\displaystyle y = A[x - h]^2 + k,](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%20%3D%20A%5Bx%20-%20h%5D%5E2%20%2B%20k%2C)
that negative in front of 
gives you the OPPOCITE outcome, so be careful.

Mean measure of central tendency is the most affected by outliers. Then the correct option is B.
<h3>What is Mean?</h3>
The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
Mean measure of central tendency is the most affected by outliers.
Then the correct option is B.
