The value of t on the closed interval for which the derivative is equals to the average rate of change is given as follows:

t = 1.75.

How to calculate the value of t?

The function in this problem is given as follows:

v(t) = 4t² - 6t + 2.

The average rate of change over an interval [a,b] is given by the change in the output divided by the change in the input, hence:

r = [f(b) - f(a)]/(b - a).

The interval is [0,3], hence the bounds are given as follows:

a = 0, b = 3.

The numeric value at these bounds is of:

  • f(0) = 2.
  • f(3) = 4(3)² - 6(2) + 2 = 26.

Hence the average rate of change is of:

(26 - 2)/(3 - 0) = 8.

The derivative is given as follows:

v'(t) = 8t - 6.

The equality is then calculated as follows:

v'(t) = 8.

8t - 6 = 8.

8t = 14.

t = 14/8

t = 7/4.

t = 1.75.
