A quadratic function y= f(x) is plotted on a graph and the vertex of the resulting parabola is (6,4). What is the vertex of the function defined as g(x) = f(-x) + 2?

Mr. jones determined that the equation y = 98 - 16/5 x could be used to predict his students' unit test scores, based on the number of days, x, a student was absent during the unit. what was the meaning of the y-intercept of the function? (by the way the 16/5 is a )
