Calculate the average rate of change of f(x) = x2 - 1 x - 3 for 1 ≤ x ≤ 3. a) - 13 3 b) - 3 13 c) 13 3 d) 3 13

3

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

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 = = = 3

you never say the total so we cant find the percentage used for petrol
