A quadratic function y, equals, f, of, xy=f(x) is plotted on a graph and the vertex of the resulting parabola is left bracket, 5, comma, minus, 5, right bracket(5,−5). What is the vertex of the function defined as g, of, x, equals, f, of, x, plus, 2g(x)=f(x)+2?
The vertex of the function g(x) is the same as the vertex of the function f(x), which is (5, -5).
Therefore, the vertex of g(x) is also (5, -5).
