Understanding the Key Features of a Parabola

This video tutorial explains the key features of a parabola, focusing on how coefficients affect its graph. It covers graphing parabolas by finding zeros and the vertex, comparing different coefficients with the parent function, and determining the axis of symmetry using various methods. An example problem is solved to illustrate these concepts, emphasizing the impact of negative coefficients on the graph's orientation and width.
