## anonymous one year ago Can someone check my work? 1. Find the period for f(x) = -7sin5x Answer: 2pi/5?

1. Nnesha

$\huge\rm y=a \sin(bx-c)$ where $\left| a \right|$ = amplitude to find period use the formula $\huge\rm \frac{ 2\pi }{ b }$

So then my answer is correct?

3. Nnesha

opps didn't see the answer yes looks correct
