from each of the given mapping notations, write the equation, in transformational form, for the sine function it represents.
a) (x,y) ----> (x - 25º, 2y +1)
b) (x,y) ---> (1/2x+30º,y)
c) (x,y) -----> (3x, 1/2y-1)
thanks
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?
