Question

the distance between the crest (highest point) and the trough (lowest point) can be calculated by subtracting the trough from the crest. what is the distance?

Explanation:

Step1: Identify crest and trough values

Crest (highest point) is at \( +7 \), trough (lowest point) is at \( -7 \).

Step2: Calculate the distance

Distance = Crest - Trough = \( 7 - (-7) = 7 + 7 = 14 \).

Answer:

14
