Answer:
-4
Step-by-step explanation:
The average rate of change is given by ...
m = (y2 -y1)/(x2 -x1)
m = (-10 -(-2))/(3 -1) = -8/2 = -4
The average rate of change on the interval [1, 3] is -4.
Answer:
27
Step-by-step explanation:
it's a lager number so it's greater
You may perform the division using either long division or synthetic division. Any preference?
I used synthetic div. with -2 as the divisor:
________________
-2 / 3 4 -10 0 15
-6 4 12 -24
-------------------------
3 -2 -6 12 -9
In factored form, with remainder, we then have:
(x+2)(3x^3 - 2x^2 - 6x + 12) remainder -9
