    -The 5 is a constant, so it should be translated 5 units up. -The -3 in front of sin means that the graph was reflected about the x axis, and has an amplitude of 3. -The 2 in front of the angle means the period is double what it normally is (2 full cycles in 2pi -The extra pi/2 inside the angle just means the graph started at x=pi/2 instead of the origin

    X+pie/2 means the graph shift in the negative x direction by pi/2 units

    The things I could do to that function... but I can't do a phase shift

    I think the first post is right, except for the phase shift correction
