Answer:
The average rate of change over the given interval is 12
Step-by-step explanation:
Here, we want to calculate the average rate of change over the given interval
Mathematically, we can calculate the average rate of change using the formula below;
f(b) - f(a)/b-a
The f values are same as the y values
Thus, we have it that;
a = 1 and b = 3
f(a) = -5 and f(b) = 19
The average rate of change is thus;
(19-(-5))/(3-1) = 24/2 = 12
