I have to find the vertex, axis, domain, & range of this quadratic equation:(adsbygoogle = window.adsbygoogle || []).push({});

f(x)= -1/2(x+1)^2 -3

I can't remember how to do the vertex. Is it y= -b/2a?

Also, I tried factoring the equation, but I think I messed up. I ended up with:

f(x)= .25x^2 +.5x-2.75

Thanks
