Answer:

The mean value of this function on the interval [7, 11] is 6.

Explanation:

The given function f(x)= x^2 - 12x + 16 has the value

f(7)= 7^2 - 12(7) + 16, or -19, at x = 7. Thus, one point on the curve is (7, -19).

The given function f(x) = x^2 - 12x + 16 has the value

f(11)= 11^2 - 12(11) + 16, or 5, at x = 11. The second point on the curve is (11, 5).

Using the mean value formula, we get:

f(11) - f(7) 5 - (-19)

------------- = -------------- = 24/4 = 6

11 - 7 4

The mean value of this function on the interval [7, 11] is 6.
