The average rate of change of the function in the given interval -3 ≤ x ≤-1 is 10.
<h3>What is the average rate of change?</h3>
The average Rate of Change of the function f(x) can be calculated as;

Interval -3 ≤ x ≤-1
a = -3, b = -1
f(a) = f(-3) = -20
f(b) = f(-1) = 0
Step 2: Find Average

Therefore, the average rate of change of the function in the given interval -3 ≤ x ≤-1 is 10.

1-
number 2) is correct
2- 3) is true
11) Jacob is not correct. because 6radical 5 is irrational
12) radical 20 is an irrational number but
so a+b is irrational
but

so b+c is rational
good luck
