Which graph represents the function y = 2 sine (one-half x) On a coordinate plane, a function has a maximum of 2 and minimum of negative 2. It completes one period at 8 pi. The curve crosses the y-axis at negative 2. On a coordinate plane, a function has a maximum of 2 and minimum of negative 2. It completes one period at 4 pi. The curve decreases through y-axis at (0, 0). On a coordinate plane, a function has a maximum of 2 and minimum of negative 2. It completes one period at 8 pi. The curve crosses the y-axis at (0, 2). On a coordinate plane, a function has a maximum of 2 and minimum of negative 2. It completes one period at 4 pi. The curve increases through the y-axis at (0, 0).
