Answer:
The reflection given as
x = 3 , 0 , -2 , -5
f(x) = 9 , 0 , 4 , 25
Thus the table no 1 is the correct option
Step-by-step explanation:
Since if we take the reflection about the y-axis then in the co-ordinates of point of function the only values of x replace by negative numbers but the values of y co-ordinates of points are not change that is the height of function does not change.
So
In the given table
when
x = -3 , 0 , 2 , 5
f(x) = 9 , 0 , 4 , 25
Now if we have to take reflection about y-axis then we have to change the signs of x-axis only So
The reflection given as
x = 3 , 0 , -2 , -5
f(x) = 9 , 0 , 4 , 25
Thus the table no 1 is the correct option
