Step 1
Let's call the line segments L1 and L2, and the quarter circle C. L1: The line segment starts at (0,0) and ends at (2,2). The slope of this line is (2-0)/(2-0) = 1. So the equation of L1 is: L1: y = x L2: The line segment starts at (2,2) and ends at (6,0). The Show more…

The graph consists of line segments and a semicircle, as shown in the figure. Evaluate each definite integral by using geometric formulas. i. ∫[0,2] f(x)dx ii. ∫[-4,2] |f(x)|dx iii. ∫[-4,6] f(x)dx
The graph of f is shown below. Evaluate each integral by interpreting it in terms of areas. 1. ∫ f(x) dx = -3/2 2. ∫ f(x) dx = -2*2 + π*1^2 3. ∫ f(x) dx = π + 0.1
