    Question Graphing Sine problem

    F(x) = -2sin(pi x - pi/2) +1 for [-2,-2]

    Amplitude: |-2|=|2|= 2

    Period: 2pi/B = 2pi/pi = 2

    Phase Shift: C/B =(pi/2)(1/pi) = 1/2

    I got this wrong in my Quiz and also i don't know how to draw graphs here in the forum. and i would like to see how this graph looks like please.

    You're pretty close, but \varphi=-\tfrac{1}{2} <---Phase Shift.

    I'm not sure I can say I'm the best. There are others better than me.

    Thanks for the compliment, though!
