The center of a circle is at (−3, 1) and its radius is 9. what is the equation of the circle? (x+3)2+(y−1)2=18 (x−3)2+(y+1)2=18 (x−3)2+(y+1)2=81 (x+3)2+(y−1)2=81

Someone answer this asap for the function f(x) and g(x) are both quadratic functions. f(x) = x² + 2x + 5 g(x) = x² + 2x - 1 which statement best describes the graph of g(x) compared to the graph of f(x)? a. the graph of g(x) is the graph of f(x) shifted down 1 units. b. the graph of g(x) is the graph of f(x) shifted down 6 units. c. the graph of g(x) is the graph of f(x) shifted to the right 1 unit. d. the graph of g(x) is the graph of f(x) shifted tothe right 6 units.
