Explanation of Solution
Given:
The given function is,
Method:
By using properties of standard
By using quadratic formula.
Calculation:
As we know, the standard form of quadratic equation is
Here, the standard form of quadratic equation of the given function is
Now,by comparing given fuction with standard form we get,
As we know,vertex of quadratic equation is
Putting the values of a,b we get the vertex as
For a quadratic equation in standard form,
Here, the axis of symmetry is
For x-intercepts put
Therefore intercepts point are
Graph:
From graph we can clearly see that the vertex of given function is
