Step-by-step explanation:
The average rate of change for the function f(x) from x=a to x=b is given by :-
The given function : (Its a quadratic function with degree 2.)
The average rate of change for the quadratic function from x=−2 to x = 5 will be :-
[Note (-)(-)=(+)]
Hence, the average rate of change for the quadratic function from x=−2 to x = 5 is 5 .

First box -plot
Step-by-step explanation:
The given data set :
Arrange in order
We can see that the smallest data value = 20 and the largest date value = 32
Median = Middle most number = 24
in a box plot , both the whisker ends represents the minimum and the maximum data value. The median value is shown by the vertical line in the box.
In the given picture only first and fourth box plot showing the correct smallest and largest value to the given data set.
But the median value is correctly represented by the first one as the fourth one has median of 25.
Hence, the correct box plot for the given data : First
