Question

A quadratic function y=f(x)y=f(x) is plotted on a graph and the vertex of the resulting parabola is (5, -4)(5,−4). What is the vertex of the function defined as g(x)=f(x)+2g(x)=f(x)+2?

    The vertex of the function defined as g(x) = f(x) +2 according to the task content is; (5, -2).

    What is the vertex of the function defined as g(x)?

    It follows from the conventional method of representing quadratic equations in vertex form as follows;
    y = a(x-h)² + k where the vertex is given as the point, (h,k).
    Hence, if the function; g(x)=f(x)+2, it follows that the vertex of the function is; (5, -4+2);
    = (5, -2).
