    as this is a normal hyperbola, no translation, so to find the vertices, just find the x-intercept.

    then change the hyperbola to standard form and use "a" and "b" to find e. the foci are \((\pm ae,0)\)

    My options: A. vertices: ( -10, 0), ( 10, 0) ; foci: (-square root of 51, 0), (square root of 51, 0) B. vertices: ( -10, 0), ( 10, 0) ; foci: (-square root of 149, 0), (square root of 149, 0) C. vertices: ( -7, 0), ( 7, 0) ; foci: (-square root of 149, 0), (square root of 149, 0) D. vertices: (0, -10), (0, 10) ; foci: (0, -square root of 149), (0, square root of 149)
