Question

The graph shows the distance y, in centimeters, a pendulum moves to the right (positive displacement) and to the left (negative displacement), for a given number of seconds x.
What is the pendulum's maximum displacement?

Answer 1

ANSWER

The pendulum's maximum displacement is 2cm.

EXPLANATION

The maximum value of the graph is the pendulum's maximum displacement.

The graph is a periodic function

The amplitude of the graph is 2.

The range of the graph is -2≤y≤2

The maximum value is 2.

The pendulum's maximum displacement is 2cm

The correct choice is B.
