Find the axis of symmetry and your vertex the x-intercepts (the points where the parabola cuts the x-axis) and the y-intercepts Graphing Quadratic Functions in Vertex & Standard Form - Axis of Symmetry - Word Problems. Explanation: Given: y=f(x)=x2+6x+5. The Vertex Form of a quadratic function is given by: f(x)=a(x−h)2+k, where (h,k) is the Vertex of the. Learn how to graph quadratic equations in vertex form. A quadratic equation is an equation of the form y = ax^2 + bx + c, where a, b and c are.
