Problem 85 of 7
Rewrite trigonometric function y=3sin(2x)+4 to reveal amplitude, period, and midline.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
factor inside argument and identify parameters.
Hidden until you reveal it.
Factor inside argument and identify parameters for sine, cosine, and tangent.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Put the argument in factored form B(x-C) when needed.
2. Read amplitude and midline for sine/cosine.
3. Compute period from the trig family and inside coefficient.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
