Which formula below gives the average rate of change of the function z(x) = -6x^2 + 3 on the interval -1≤x≤2?

Step-by-step explanation:

The average rate of a function f(x) is interval [a,b] is given by :-

The given function:

Interval : [-1,2]

Then using the above general formula , the average rate of change of the function z(x) = -6x^2 + 3 on the interval -1≤x≤2 is given by :-

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
