Answer:
2.5
Step-by-step explanation:
The average rate of the function f(x) from x=a to x=b is given by:
From the question, the exponential function goes through (0,30) and (20,80).
This implies that f(0)=30 and f(20)=80
Therefore the average rate of change from x = 0 to x = 20 is
The second choice is correct
