A linear function g models a relationship in which the dependent variable increases 3 units for every 1 unit the independent variable increases. Graph g when g(0) = 3. Identify the slope, y­intercept, and x­
intercept of the graph.
A submersible that is exploring the ocean floor begins to ascend to the surface. The elevation h (in feet) of the submersible is modeled by the function h(t) = 650t − 13,000, where t is the time (in minutes) since the submersible began to ascend.
a. Graph the function and identify its domain and range.
b. Interpret the slope and the intercepts of the graph.
