Question

sarah is excited for the first snow of the year! throughout the day, she notices that the snow fell heavily at first and then slowed for a while. toward the end of the day, the snowfall increased briefly again and then tapered off. which graph could show the total amount of snowfall over the course of the day?

Explanation:

Step1: Analyze snowfall trend

Total snowfall (y - axis) should always increase or stay same (since snow accumulates, it can't decrease). First graph has decreases (dips), so it's invalid. Second graph: starts with steep increase (heavy snow), then slower (flatter), then brief increase (steeper), then tapers (flattens), matching the description.

Answer:

The second graph (right - hand side graph) where the total snowfall (y - axis) is a non - decreasing function of time (x - axis), with the slope (rate of snowfall) being steep initially, then less steep, then steeper briefly, and then less steep as the snowfall tapers off.
