The parent function f(x) = x^2 is reflected across the x-axis, vertically stretched by a factor of 3, and translated right 7 units up to create g. Use the description to write the quadratic function in vertex form. A) g(x) = 7 (x+3) ^2
B) g(x) = -3 (x-7) ^2
C) g(x) = -3 (x+7) ^2
D) g(x) = 3 (x-7) ^2

Please I need major help.
