Step-by-step explanation:
is there any value for S??
Answer: 25/7
Decimal form 3.57143.....
The order goes 4, 3, 2, 1
First, simplify the expression of the function
highlighting the perfect square:

Then find the vertwx of parabola. When x=2, f(2)=2 and the coordinates of the vertex are (2,2). The axis of symmetry passes through the vertex and is parallel to the y-axis. Therefore, its equation is x=2 (see attached graph for details).
Answer: x=2.
