In a charity race, a water stand for the runners is halfway between the start and finish lines. The absolute value function y = |(x/8) - 3|models Riley’s distance y in miles from the water stand x minutes into the race. The function y = |(x/10) - 3| models Dean’s distance from the water stand during the same race. Compare Dean’s graph to Riley’s graph. What can you conclude about Dean’s speed?
Identify a, b, and c.
• a = -1 : graph opens downward and width is unchanged
• b = 0 : no horizontal translation
• c = 0 : no vertical translation

g(x) = 2|x + 1| = 2|x – (–1)| + 0.
• a = 2 : graph is narrower
• b = –1 : translated 1 unit left

g(x) = -|x - 3| + 2 = -1|x – 3| + 2.

• c = 2 : translated 2 units up
y = |(x/8) - 3| is graphed in blue.
y = |(x/10) - 3| is graphed in red. Both graphs start at the same point, but Dean’s graph is translated to the right. It takes him more time to reach the water stand and to finish the race. Therefore, he is running more slowly than Riley.
