Axis of symmetry means the middle x-coordinates of the parabola. So in order to find the x value, you have to find the TP which is Turning Point by using Completing the Square :

Let y = 0,







Next, you have to solve the x value :
x + 3 = 0
x = -3
Answer:
Option C is correct.
Step-by-step explanation:
We have been given the graph
The graph is not of exponential function
Therefore, option A and B are discarded.
Now, We can see the graph is starting from 37
And the difference between Amount of water from the table is 19-22 that is -3
So, the graph is arithmetic
So, applying the formula
; d is common difference here we have d= -3

Therefore, option C is correct.
