Final answer:
To graph the function that models the height over time of a shallow-water sensor, plot the values of height on the vertical axis and time on the horizontal axis. Mark any intercepts that are reasonable within the domain and range.
Step-by-step explanation:
To graph the function that models the height over time of a shallow-water sensor, we need to plot the values of height (y) on the vertical axis and time (t) on the horizontal axis. The function given is y(x, t) = -2.77e, where e is a constant.
To mark the vertex, we need to find the highest or lowest point on the graph. Since the equation does not include any quadratic terms, we can't determine a specific vertex.
However, we can mark any intercepts that are reasonable within the domain and range of the situation. For example, if the height of the sensor at time t = 0 is 0.5 meters, we can plot a point at (0, 0.5) on the graph.
