Question

1. this graph represents a city’s high temperatures over a 10 - day period. determine whether this statement is true or false: the high temperature is a function of the day. explain your thinking.

Explanation:

A relation is a function if each input (day) has exactly one output (high temperature). Looking at the graph, each day (1 through 10) corresponds to only one high temperature value; there are no days with two different temperature data points. This satisfies the definition of a function.

Answer:

True, because each day (input) has exactly one corresponding high temperature (output), which meets the criteria for a function.
