Question

Determine the amplitude of the following function:y=−4/5tan(−4x)

Answer 1

Answer:

  ∞

Step-by-step explanation:

In many instances, the term "amplitude" is used to refer to half the range. The range of any tangent function is (-∞, ∞), so its amplitude is ∞ regardless of any multiplier or offset.

Perhaps you're expected to say the absolute value of the coefficient of the trig function. In that case, the "amplitude" is 4/5.
