Your answer does not match any of the choices. Please help. g(x) = (x - 6)2 g(x) = (x + 18)2 g(x) = (x + 6)2 - 12 g(x) = (x + 6)2 + 12

Math
Determine the equation of g(x) that results from translating the function f(x) = (x + 6)2 to the right 12 units. g(x) = (x - 6)2 g(x) = (x + 18)2 g(x) = (x + 6)2 - 12 g(x) = (x + 6)2 + 12
