## anonymous one year ago What are the amplitude, period, phase shift, and midline of f(x) = –3 sin(4x – π) + 2?

u shouldn't need it if u know how to do it @stratemeyerjr

$f(x) = Asin B(x-C)+D$ factor out 4 to get in that format $f(x) = -3 \sin 4(x - \pi/4)+2$ |A| = amplitude midline: y = D Period (2π)/B phase shift = C

so amplitude is never negatvie right

5. anonymous

right, it's a measure of distance

ok thanks

you're welcome
