State domain, range, period, vertical asymptotes, zeros, symmetry and y-intercept of y = -2tan(3x + 180°) + 3

I just need to know if there is a formula to find the vertical asymptotes, symmetry, and zeros or do I have to solve it graphically.

Thanks.

1. You can get the vertical asymptote by solving dy/dx = infinity

You can get the y intercept by solving
y = f(0)= 2 tan(180) + 3 = 3
