Sinusoidal graphs question

[From: ] [author: ] [Date: 12-04-16] [Hit: ]
......
How does one know if the graph is reflected in the x axis due to a negative ''a'' value or there is just a phase shift (Horizontal translation)? Or are they the same thing?

-
They are the same thing
for example
y = - sinx is reflected the x-axis
y = - sinx = sin(x + pi) is horizontal translation
