Graph the function: y=12cos (x+π).

Question

I need assistance in how to find the points on this equation

Answer 1

The argument (x + π) indicates that you shift everything π units to the left. I would recommend shifting all asymptotes and x-intercepts as those would be the easiest to use.

Now, the coefficient of 12 indicates that after everything is shifted, you multiply all y-values by 12.
