Interpreting Quadratic Functions in Standard Form 1.3 - Solution

arrow_back Return to Interpreting Quadratic Functions in Standard Form

Consider the general expression of a quadratic function, where Let's note three things we can learn from this equation.

We will start by identifying the values of and We can see that and Since the intercept is given by the value of we know that the intercept is Let's now substitute and into to find the axis of symmetry and the coordinate of the vertex.
Simplify
The equation of the axis of symmetry is and the coordinate of the vertex is
