Hello,
There is no X intercept but there is a Y
Y intercept = (0,-7 + 2 square root of 13),(0,-7,- 2 square root 13)
Center (-7,0)
Vertices: (−7+√x2+52,0),(−7−√x2+52,0)
(-7+x2+52,0),(-7-x2+52,0)
Foci: (−
42−√42(x2+52) 6 ,0),(−
42+√42(x2+52)
6
,0)
(-42-42(x2+52)6,0),(-42+42(x2+52)6,0)
I honestly dont know what your trying to solve so im guessing thats what you wanted...
