Question

with aging, body fat increases and muscle mass declines. the graph to the right shows the percent body fat in a group of adult women and men as they age from 25 to 75 years. age is represented along the x - axis, and percent body fat is represented along the y - axis. state the intervals on which the graph giving the percent body fat in men is increasing and decreasing. on what interval is the graph increasing? a. (55,75) b. (20,26) c. (25,75) d. (25,55) on what interval is the graph decreasing? a. (55,75) b. (25,55) c. (25,75) d. (20,38)

Explanation:

Step1: Analyze men's increasing interval

Look at the men's line on the graph: from age 25 to 55, the percent body fat (y-value) rises as age (x-value) increases.

Step2: Analyze men's decreasing interval

Look at the men's line on the graph: from age 55 to 75, the percent body fat (y-value) falls as age (x-value) increases.

Answer:

On what interval is the graph increasing?
D. (25,55)

On what interval is the graph decreasing?
A. (55,75)
