Step-by-step explanation:
There are many methods to find the vertex of a quadratic function. The method that I will show you is by using the roots of the function
In the case of this function, the roots are ..
The vertex of a function will always be directly between these roots. The number that is directly between -1 and -3 is -2. This means that the x-value of our vertex is -2.
Now that we have the x-value, we can plug this into the function in order to get our y-value.
We have found that our y-value is -2. This means that the coordinates of the vertex are
