Question

PLEASE HELP!!! I DONT HAVE ENOUGH POINTS TO POST MORE THAN ONCE!
The table defines a quadratic function what is the average rate of change between x=-1 and x=1

Please help!! if you know of someone who posted the response please link it!!!! I need the answer now!!

Answer 1

Answer:

-3.

Step-by-step explanation:

In the table, the y value goes down by -4 and then -2, for a total of -6.

We did this over a period of two units (To go from -1 to 1, we add 2).

-6/2 = -3.

-3 is the average rate of change over the interval.

Answer 2

Answer:

-3

Step-by-step explanation:

So, heres hopefully what you're looking for. I answered the last one for you, but i cant promise everything on this one lol. Looking at the table, you decrease on the Y from five to one. Thats moving four times. Then the next part, negative one to one. Thats 2 times, coming for a total of 6 movements. Now, to find average rate of change. 6/2. Thats positive 3, and something is wrong with it. Its missing its negative! Heres why, you are decreasing not only on Y, but on X. During decrease, it NEEDS that negative or the answer is completely incorrect. PLEASE do NOT forget... Rate Of Change does not stay consistant. Every single time your moving from something different than these numbers, you gotta be careful and recalculate it or its completely wrong.

I'm here to help. Give me a shout. Sorry if that wasnt too clear, I tried
