Identify the form of a quadratic function that immediately reveals a given feature of that function. Features in question are the y-intercept of the graph, the zeroes ("roots") of the function, and the …

Graph quadratic functions given in any form.

Let's do a few more of these where we're comparing different functions. One of them that has a visual depiction, and one of them where we're just given the equation.

Solve real-world word problems that involve quadratic models. In this exercise, that models are given in standard form.

Different forms of quadratic functions reveal different features of those functions. Here, Sal rewrites f(x)=x²-5x+6 in factored form to reveal its zeros and in vertex form to reveal its vertex.

Sal finds the zeros, the vertex, & the line of symmetry of quadratic functions given in vertex form, factored form, & standard form.
