Question

at a delivery company, the cost for mailing a package depends on its weight, according to the graph shown. what is the range of the function shown? 0 ≤ y ≤ 35; 10 ≤ y ≤ 40; y ≤ 40; y ≥ 10

Explanation:

Step1: Recall Range Definition

Range of a function is the set of all possible output (y - values) of the function.

Step2: Analyze the Graph's y - Values

From the graph, we can see the minimum y - value (cost) is 10 (at points like (0,10), (5,10)) and the maximum y - value is 40 (from (25,40) to (35,40)). So the y - values (costs) range from 10 to 40, inclusive.

Answer:

\(10\leq y\leq40\) (corresponding to the option "10 ≤ y ≤ 40")
