Answer:

Step-by-step explanation:
The first function is
.
We make y the subject of this function to obtain,
.
This is graph will open downwards because
.
At y-intercept of this graph,
.


The y-intercept is
.
At x-intercept
.


.
The x-intercepts are,

Also the vertex form of the function is,
.
Therefore the vertex of the parabola is
.
We plot all the points obtained and draw a smooth curve to obtain the curve as show in the diagram.
The second function is


This is the graph of the basic quadratic function
that has been turned upside down.
This graph also has the vertex,y-intercept and x-intercept all at
.
We now graph this too on the same graph sheet as the first one to obtain the blue graph as shown in the diagram.
These two graphs intersect at the point,
.
Therefore the correct answer is B
