~offering 15 points~ which function’s domain consists of all real numbers greater than 3? a) f(x) = 3x b) f(x) = the square root of x c) f(x) = 3x + 4 d) f(x) = 1 over the square root of x - 3

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142
