d. is the graph increasing, decreasing, or constant? explain.
choose the correct answer below.
a. the graph is increasing because as the input values increase from left to right, the graph goes up to the right.
b. the graph is increasing because as the input values increase from left to right, the graph goes down to the right.
c. the graph is constant because as the input values increase from left to right, the graph is horizontal.
d. the graph is decreasing because as the input values increase from left to right, the graph goes up to the right.
e. the graph is decreasing because as the input values increase from left to right, the graph goes down to the right.

Explanation:

In a graph, if as the input (x - values, here years since 1950) increases from left - to - right and the output (life expectancy) goes up to the right, the graph is increasing. Looking at the life expectancy values which increase with the increase in years since 1950, the graph representing this data would go up as we move from left to right.

Answer:

A. The graph is increasing because as the input values increase from left to right, the graph goes up to the right.
