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.
 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
 
        
             
        
        
        
Answer:
C
Step-by-step explanation:
There’s nothing hard with this
You need to know special right triangles
This is a 30,60, 90 triangle
We automatically know becuase theres. Right angle (90) and a 60 degree angle
now the formula is the smallest side is (n) {I’m using N becuase theres already an X) or in this case, 6
The hypotenuse, the one directly above the 2nd biggest side, or the diagnoal side is 2n or (12). Now we know what X is in this situation which is 12. So that narrows it to 2 answers 
Now the side on the bottom of the hypotenuse, the second biggest side is used in the formula N . So we know what N is in the beginning, 6 so we just plug that in and well get C. Attached is a photo on q 30, 60, 90 special right triangle

y increases as x increases
