Answer:
The vertex for each quadratic is 
Step-by-step explanation:
To determine the vertex for each quadratic,
The vertex of the
coordinate can be determined using the formula,

The standard form of the quadratic function is

Hence, for the given equation of the quadratic function,



and 
Hence,
becomes,



∴
This is the vertex for the 
To determine, the vertex for the 
We will put the value of the vertex of the
in the equation and write

Then,


This the vertex for the 
Hence,
