Which equation, when graphed, has x-intercepts at (8,0) and (-2,0) and a y-intercept at (0, -48)? f(x) = -3(x - 3)(x + 2)
f(x) = -3(x + 8)(x - 2)
f(x) = 3(x - 3)(x + 2)
f(x) = 3(x + 3)(x - 2)

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle? a) (x + 5)2 + (y + 3)2 = 18 (x + 5)2 + (y + 3)2 = 3.72 (x - 5)2 + (y - 3)2 = 18 d) (x - 5)2 + (y - 3)2 = 32
