Question

for each scenario below, choose the best graph.
(a) a plane goes slower after landing.
(b) manuel climbs up a ladder to the roof.

Explanation:

Step1: Analyze plane - landing scenario

The speed of the plane decreases over time after landing. A decreasing - function graph represents this.

Step2: Analyze Manuel - climbing scenario

Manuel's distance above the ground increases as time passes while he climbs the ladder. An increasing - function graph represents this.

Answer:

(a) The graph where the plane's speed is a decreasing function of time (the second graph in the first set).
(b) The graph where Manuel's distance above the ground is an increasing function of time (the first graph in the second set).
