• trig -

y = sin(-3x + 3)
sin (-a) = -sin a
so I am going to say
y = -sin (3x-3)

Amplitude = 1 implicitly
Period =
from x = 0 to 3x = 2 pi or x = (2/3) pi so period = 2 pi/3
Two x- intercepts =
y = 0 when 3x-3 = 0 or x = 1
y = 0 when 3 x - 3 = pi or x = (pi + 3)/3
y - intercept =
when x = 0, y = - sin 3
Domain = all real x
Range = -1 </= y </= +1
Shift along x = when angle is -3
Shift along y = none
Kind of reflection = do not know what this means
