Choose the graph of the following function: f (x) = -1/3cosine (2x)
Graph A
On a coordinate plane, a function has a maximum at (0, 0.25) and then curves down through (1, 0) to a minimum of (2, negative 0.25).
Graph B
On a coordinate plane, a function has a maximum at (0, 2), and curves down through (5, 0) to minimum (9, negative 2). It then curves up again through (14, 0).
Graph C
On a coordinate plane, a function has a minimum at (0, negative 2) and curves up through (4, 0) to maximum (10, 2). It then curves down through (14, 0).
Graph D
On a coordinate plane, a function has a minimum at (0, negative 0.25) and curves up through (0.5, 0) to (1, 0.25). It then curves down through (2, 0) to (3, negative 0.25).
