Here, A polynomial f(x) is given in the Question and we have to find the value of f(1/2). This can be done by substituting x by 1/2.
Given,

So, replace every x in this expression by 1/2, because we have to find the value of f(1/2)


So, let's simplify it by solving further,


So, the final value of f(1/2) is 14/3 that is around:

And we are done !!
