Final answer:
To find the average of the function f(x) = -(1)/(x+3) over the interval [-1,1], the average is -1/3.
Step-by-step explanation:
To find the average of the function f(x) = -(1)/(x+3) over the interval [-1,1], we need to evaluate the definite integral of f(x) over that interval and divide it by the length of the interval. The average can be calculated using the formula:
Average = (1/length of interval) * ∫(lower limit to upper limit) f(x) dx
For the given function f(x) = -(1)/(x+3), the average can be found by evaluating the definite integral:
Average = (1/2) * ∫(-1 to 1) -(1)/(x+3) dx
By simplifying the integral and performing the calculations, the average of f(x) over the interval [-1,1] is:
Average = -1/3
