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

From the graph, the crest (highest point) is at \(+7\) and the trough (lowest point) is at \(-7\).

Step2: Calculate the distance

Subtract the trough value from the crest value: \(7 - (-7)\). Using the rule of subtracting a negative (which is adding the positive), we get \(7 + 7 = 14\).

Answer:

14
