Answer:
Option C =
Step-by-step explanation:
As you can see from the graph, one of the points lying on the graph is (3,1).
Inserting this point in above all equations, we get,
1] <em> = -1</em> , which is not equal to 1.
2]<em> </em>= 4.464 , which is not equal to 1.
3]<em> = 1</em> , which is equal to 1.
4] <em> = 2.464</em> , which is not equal to 1.
Thus, only option 3 satisfies the point.
One can also check for other points.
