Choose the graph of the following function: f (x) = negative 2 cosine (0.5 x)
Graph A
On a coordinate plane, a function curves down through (0, 0) to (3, negative 2), curves up through (6, 0) to (9, 2), and curves down through (12, 0).
Graph B
On a coordinate plane, a function has a minimum at (0, negative 2) and increases through (3, 0) to (6, 2), and then decreases through (9, 0).
Graph C
On a coordinate plane, a function has a minimum at (0, negative 2) and increases through (0.5, 0) to (1.5, 2), then decreases through (2.5, 0) to (3, negative 2).
Graph D
On a coordinate plane, a function increases through (0, 0) to (0.5, 2) and decreases through (1.5, 0) to (2.5, negative 2).
