What is the amplitude of \(y=5\sin x - 2\)?

Let's work it out together.

Work through one checkpoint at a time. Your answer area opens after the reasoning.

Checkpoint 1

In \(y=A\sin(Bx)+D\), amplitude is \(|A|\).
Checkpoint 2

The outside constant D moves the midline but does not change amplitude.
Checkpoint 3

Amplitude is a nonnegative vertical distance.
