why is the range [-1/2,1/2] for question 52, but not [-1, 1] forquestion 50?
50. Sketch the graph of the following function. Determine the domain and range of the function by examing its graph. f(t) = -1 + sin t a. Domain: (-∞, co); Range: [-1, 1] b. Domain: (-∞, ∞); Range: [-2, 0] c. Domain: (-∞, ∞); Range: [0, 2] d. Domain: (-∞, ∞o); Range: [-2, 1]

52. Sketch the graph of the following function. Determine the domain and range of the function by examing its graph. f(t) 1 = cos t a. Domain: (-∞, ∞); Range: [-3/2, 3/2] b. Domain: (-∞, ∞); Range: [1/2, 3/2] c. Domain: (-∞, ∞); Range: [-1/2, 1/2] d. Domain: (-∞, ∞); Range: [-3/2, 1/2]
