How would you describe the difference between the graphs of f(x) = x ^ 2 + 4 and g(y) = y ^ 2 + 4 oa. g(y) is a reflection of f(x) ) over the line y = 1 . o o b. g(y) is a reflection of f(x) ) over the line y=x 1 g(y) is a reflection of f(x) over the x-axis od. g(y) is a reflection of f(x) over the .
