Let f (x) = | + 2 on [-5, 1). What is the average value of f ? For what values of x does the average value occurs? Show all your work. For an indefinite integral, use the notation INT in place of the symbol. For example, S' (x + 1) dx should be written as INT (x + 1) dc. For a definite integral, use the notation INT (a, b). For example, (z + 1) dx should be written as INT (1, 2) ( + 1) dec. For a definite integral that has been integrated, use the notation EVAL (a, b). For example, (2 +2) should be written as 2 +2 EVAL (1, 2)
