Answer:
A
Step-by-step explanation:
The average rate of change of f(x) in the close interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 0, 3 ]
From the graph
f(b) = f(3) = 4
f(a) = f(0) = - 3 , thus
average rate of change = [tex]\frac{4-(-3)}{3-0}[/tex] = [tex]\frac{7}{3}[/tex] → A
