Quadratic function. -Analysis of concavity. -Axis of symmetry. -Vertex and its interpretation. Intersection with the coordinate axes. -Graph and its analysis. If you do not remember how to solve quadratic equations or want to reinforce, I leave you the links: Quadratic equations with absence of coefficients, quadratic equations where the trinomial is factorable. • Quadratic equations Quadratic equations using their general formula • Quadratic equations using the general formula...
