It can give us lots of information about the quadratic function like location of vertex, domain, range, axis of symmetry, minimum or maximum value etc. In this article if you stay with me you can easily learn how to find all these variables.
We need to use cosine law in order to find all the angles if we are given with all the sides. [Read more…]
We have already drawn the most basic form of quadratic function which is
in the post https://mathinstructor.net/2018/07/quadratic-functions-pre-calculus-grade-11-post-2/. What is the vertex of such a quadratic function?
What is the meaning of y-intercept? y-intercept is the point where graph cuts y-axis which means x-value at that point is equal to 0.
