Let f(x)=−1/4(x+4)^2−8 . What is the average rate of change for the quadratic function from x=−2 to x = 2? Enter your answer in

kiruha [24]

Answer:

Average rate of change of function is -2.

Step-by-step explanation:

Given $f(x)=\frac{-1}{4}(x+4)^2-8$ .

we have to find the average rate of change for the quadratic function from x=−2 to x = 2.

$f(-2)=\frac{-1}{4}(-2+4)^2-8=\frac{-1}{4}(4)-8=-9$

$f(2)=\frac{-1}{4}(2+4)^2-8=\frac{-1}{4}(36)-8=-17$

The average rate of change of the function f(x) on interval [-2,2] is

$\frac{f(b)-f(a)}{b-a}=\frac{f(2)-f(-2)}{2-(-2)}=\frac{-17-(-9)}{4}=\frac{-8}{4}=-2$

What is the third quartile of the following data set 24,20,35,39,28,42,25,29,44,21,37

strojnjashka [21]

First, arrange the data:

20, 21, 24, 25, 28, 29, 35, 37, 39, 42, 44

You can use the formula 3/4 multiplied by the number of data + 1 to find the position of the 3rd quartile.

so it's going to be 3/4 x (11+1) = 9th position

the number in 9th position is 39 so that's the 3rd quartile
