Answer:
option (d) is correct.
Step-by-step explanation:
Given :
We have to choose out of given option which represent f(x + 1)
Consider the given function
Since we have to find f( x + 1 ) , replace x by x + 1 in the given function f(x) , we have,
Using algebraic identity, , we have,
Simplify the expression by multiplying 2 with each term in bracket, we have,
Simplify , we have,
Thus, option (d) is correct.
