(y+1)^2/4 - (x-2)^2/16 = 1
so i know how to graph it....
i know the center is (-1,2)
Am I right the to say the a-value is 2 or is it +and- 2
and the b-value is 4 or is it +and- 4
and finally how do you find the domain and range?
is the range 0 less than or equal to y greater than or equal 4
and the domain all real?
