How is the graph of y=-1/3x^2-4 related to the graph of f(x)=x^2? Algebra Quadratic Equations and Functions Quadratic Functions and Their Graphs 1 Answer Tony B Feb 17, 2017 See explanantion Explanation: color(blue)(1->)The general shape of the graph y=x^2 is that of uu color(blue)(2->)The -4 lowers the graph of y=x^2 by 4 color(blue)(3->)Putting a minus sign in front of the x^2 so that we have y=-x^2-4 turns the whole thing upside. Now we have the general shape nn color(blue)(4->)the 1/3 in y=-1/3x-4 has the effect of widening the graph Answer link Related questions What are the important features of the graphs of quadratic functions?
