Lesson: Features of Quadratic Functions Mathematics • 9th Grade

Students will be able to

• find the key features of a quadratic equation from its equation or graph, including its intercepts, vertex, axis of symmetry, domain, and range,
• understand that quadratics are symmetric in the vertical line through their vertex,
• understand that the sign of the leading coefficient tells us the type of extrema that the quadratic function will have,
• recall and apply the formula for the axis of symmetry using the coefficients of the quadratic.
