Answer:
Symmetry about y-axis
Step-by-step explanation:
We are given that
When the graph is symmetric about x- axis then the point (x,y) change in to (x,-y) and the function remain same.
The point is replaced by
Substitute the value then we get
(
The value of function changes .Hence , the function is not symmetric about x- axis.
When the function is symmetric about y-axis then the point change into point and function remain same
Substitute the value
()
The value of function does not change when point change ,Hence, the function is symmetric about y- axis.
When the graph is symmetric about origin then the point change into point and the value of function remain same.
Substitute the value then we get
Hence, the graph has symmetry about y-axis .
