Answer: Option D: x-axis symmetry
Step-by-step explanation:
The symmetry concept can be explained as below:
- If any point say, (x,y) on the graph, then (x,-y) is also on the graph, it shows x- axis symmetry.
- If any point say, (x,y) lies on the graph, then, (-x,y) should also lie on the same graph, then is shows y-axis symmetry.
Now, here the graph is for x = y^{2}-100 is attached.
Suppose, (x,y) = (-100,0)
then, solving this point satisfies the equation of given graph.
Also, (x,-y) = (-100,0) satisfies the equation of the given graph.
Hence, the relation x = y^2 – 100 is symmetrical to x-axis.
