Answer:
Option d is right
Step-by-step explanation:
A function is called one to one if two x will not have same y value.
In other words, in the domain each x is matched with a unique y and if x1 not equals x2 we have the corresponding y1 will not be equal to y2.
In the graph given, we find that the y value say 1 has preimages in both to the right of y axis and to the left of y axis.
Hence this is not one to one.
This is a function because each x has a unique image. If we draw a vertical line in any part of the graph we find that it cuts only one time the graph of f(x)
Hence f is a function but not one to one. A one to one function need not pass through the origin.
Hence we find that of the options given, a,b and c are wrong.
But option d is right.
Answer:
(4,1), (-4,1), (4,6), (-4,6)
Step-by-step explanation:
Here can be identified two points with the same 'y' value: (4,1), (-4,1)
it means that there is a line passing by y=1
Same for (4,6), (-4,6): it means that there is a line passing by y=6
Now find the distance between two points in both cases
-42 x 27 = -1,134 Hope this helped!
