Concept:Use the argument of the function to find the required value of x, then substitute it into the given expression.Explanation:We are given f(x−1)=x3+3x2+4x−5.To find f(2), set x−1=2.So, x=3.Now substitute x=3 into the expression:f(2)=(3)3+3(3)2+4(3)−5f(2)=27+27+12−5f(2)=61.Answer:61 (Option A).
