The function () = -4.877 + 18.754 is used to model the height of an object projected in the air, where h(t) is the heigh in meters and t is the time in seconds. What are the domain and range of the function h(t)? Round values to the
nearest hundredth.

The graph of the quadratic function shown on the left is y = –0.7(x + 3)(x – 4). the roots, or zeros, of the function are . determine the solutions to the related equation 0 = –0.7(x + 3)(x – 4). the solutions to the equation are x =
