(1 point) Suppose 4 2 (a) Evaluate the definite integral by interpreting it in terms ot signed area. f(x) dx if 4 < x < 10, if 10 < x < 16. Suggestion: Draw a picture ot the region whose signed area is represented by the integral. Then find the signed area using formulas trom nigh school geometry. (5) Find the average value ot f(x) over the interval [4, 16]. Average value
