Using the Vertical Line Test, the graph does not represent a function is ellipse, the third graph.
<h3>What is vertical line test?</h3>
The vertical line test is a graphical method of determining whether a curve in the plane represents the graph of a function. It is done by visually examining the number of intersections of the curve with vertical lines.
Any vertical line in the x y plane must intersect the graph of a function at most once.
In the given graphs, the graph of a function intersects the y axis twice. So, it is not a function.
From the given graphs, the third graph which is of ellipse crosses the vertical line twice.
Thus, the graph does not represent a function is ellipse.

Answer:
2.
Domain: all real values of x
Range: f(x)》-4
3.
Domain: all real values except x = 0
Range: All real values except f(x) = 0
Step-by-step explanation:
2.
Domain: all real values of x
Range: f(x)》-4
Because this is a concave up quadratic with a minimum turning point at (0,-4)
3.
Domain: all real values except x = 0
Range: All real values except f(x) = 0
Since x is in the denominator, it can't be 0
For f(x) = 0, x has to be infinity

Hello there awesome brainly user!
To convert
to a mixed number you have to divide 31/6 which equals 5 R 1 Remember that the remainder is the numerator and the whole number is 5. So, the mixed fraction is

Thanks and have a good day.
Let the x ml of water be mixed with 237 ml of ammonia whose strength is 100%, in order to create a mixture of 75% strength.
The equation required to solve this will be:
237/(237+x)=75/100
solving for x we get:
237/(237+x)=3/4
237×4=3(237+x)
948=711+3x
3x+711=948
3x=948-711
3x=237
x=237/3
x=79 ml
therefore the amount of water to be added will be 79 ml
