    Trig Help !!! please help me

    from each of the given mapping notations, write the equation, in transformational form, for the sine function it represents.

    a) (x,y) ----> (x - 25, 2y +1)

    b) (x,y) ---> (1/2x+30,y)

    c) (x,y) -----> (3x, 1/2y-1)



    thanks

    Re: Trig Help !!! please help me

    If I'm not mistaken, (Which I may be) to go

    a) for f(x), your input is x-25 -> f(x-25). Then, you are doing 2*f(x-25)+1
    Since f(x) is the sine function, you end up with 2sin(x-25)+1

    Do you think you can follow the same pattern for the rest?
