Answer:
x = -1 ,+1
Step-by-step explanation:
Let y be a function of x given in question
Simply differentiate it to get it's derivative and then equate to zero to find it's extremams.
Now equate it's derivative to zero.
=0
So, after solving we get
x=0,1,-1
Now by graphical interpretation we can observe that it is even function thus it is symmetric about Y axis. Also it passes through origin.
At minus and plus infinity of x y tends to minus infinity.
Also check nearby values to 1 or -1.
Thus at -1 and +1 there is maxima symmetrically.
The Decimal greater then that is 2.35
