This post explains and give practice opportunities related to TEKS A.7A:
graph quadratic functions on the coordinate plane and use the graph to identify key attributes, if possible, including x- intercept, y- intercept, zeros, maximum value, minimum values, vertex, and the equation of the axis of symmetry
Students learn to identify the vertex, minimum value, and maximum value of quadratic function graphs.
Students also learn to identify the zeros and the intercepts of a quadratic function graph.
Finally, students learn to identify the axis of symmetry using visual cues and a formula.
Between 2016 and 2023 (including redesign practice), this readiness standard has been tested 16 times on the STAAR test. Videos explaining the problems can be found below. If you'd rather take a quiz over these questions, click here. The videos below are linked to the questions in the quiz as answer explanations after the quiz is submitted.
