Interpreting Quadratic Functions in Vertex Form

Interpreting Quadratic Functions in Vertex Form 1.15 - Solution

arrow_back Return to Interpreting Quadratic Functions in Vertex Form
We want to write the vertex form of the parabola whose vertex is and passes through point To do so, let's first recall the vertex form of a quadratic function. In this form, is the vertex of the parabola. Since we are given that the vertex of our function is we have that and We can use these values to partially write our equation. Finally, to find the value of we will use the fact that the function passes through We can substitute for and for in the above equation and solve for
Solve for
Now that we know that we can complete the equation of the function.
