Answer :
After calculating the individual function values average rate and applying the formula, the answer is 368.
The average rate of change of a function can be found using the formula: (f(b) - f(a)) / (b - a). Here the function f(t) = 23t^2, and we need to find the average rate of change from t=7 to t=9.
First, calculate f(9) and f(7). f(9) equals 23*(9^2) = 1863 and f(7) equals 23*(7^2) = 1127.
Then, use the formula: (f(9) - f(7)) / (9 - 7) = (1863 - 1127) / 2 = 368.
So, the average rate of change of the function f(t) = 23t^2 from t=7 to t=9 is 368.
