Rachelle is watching a bug crawl toward her on a sidewalk. As the bug gets closer to her, she stomps her foot to startle the bug, which becomes stationary for some time and then crawls away from her quickly. The graph shows the bug's distance from Rachelle. What is the range of the graph?
please help this depends on my grade

D) 100 ≤ y ≤ 400

Explanation:

When we are talking about range, we are talking about y values, so B is disqualified.

When determining range you want the lowest & highest y values.

On this graph the lowest value of y is 100 (seen between 5 and 6 seconds).

The highest value of y is 400 (seen at 8 seconds).

Therefore, 100 ≤ y ≤ 400.

D) 100 ≤ y ≤ 400

Step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
