Question : 131) The following graph approximates the number y, in thousands : 2139446

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]

132) The following graph approximates the average monthly cable TV rates, in dollars, since 1980. The equation of this graph is given by

R = -0.0036t3 + 0.13 t2 - 0.073t + 7.7
