Solve the problem.

131) The following graph approximates the number y, in thousands, of graduates from nursing schools in the U. S. since 1985(Source: Statistical abstract of the US). The equation of this graph is the function given by

y = -0.036t4 + 0.605t3 - 1.87t2 - 4.67t + 82.5 Use the graph to approximate the domain and range of the function.

A) Domain: (-∞, ∞), Range: [0, 95]

B) Domain: [0, 13.1], Range: [0, 95]

C) Domain: [0, 13.1], Range: (-∞, ∞)

D) Domain: [0, 95], Range: [0, 13.1]
