[tex]Answer: \\ f(1) = - 3 \\ f(3) = 3 \\ Average \: rate \: of \: change: \\ \frac{f(3) - f(1)}{3 - 1} = \frac{6}{2} = 3[/tex]
Answer:
3
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
here [ a, b ] = [ 1, 3 ]
f(b) = f(3) = 3² - 3 - 3 = 9 - 3 - 3 = 3
f(a) = f(1) = 1² - 1 - 3 = 1 - 1 - 3 = - 3
average rate of change = [tex]\frac{3+3}{3-1}[/tex] = [tex]\frac{6}{2}[/tex] = 3
