In this post, we will discuss about most basic quadratic function which is
. We will plot this function using different
values and will analyze the shape of such a function.
Lets plot function
, Lets take value of
and
. We will get following:
Now, we will plot these set of points (0,0), (-1,1), (1,1), (-2,4). (2,4) and check the shape of this graph.
Every quadratic function is going to look similar to this but it may change width, direction of opening and its vertex which is (0,0) in this case. Direction of opening in this case is upwards. In the next post, we will discuss vertex form of quadratic functions.
