f(-1) = (-1)^3 + 2 = -1 + 2 = 1
["Understanding f(-1) = (-1)³ + 2 = 1: A Simple Mathematical Breakdown", "When solving mathematical expressions, clarity and precision are key—especially when working with exponents and function evaluation. One elementary but instructive example is computing ( f(-1) ) where ( f(x) = (-1)^3 + 2 ). Let’s break down this expression step by step to understand how we arrive at the result:", "[\nf(-1) = (-1)^3 + 2\n]", "First, examine the exponent:\nThe expression ( (-1)^3 ) means multiplying (-1) by itself three times:\n[\n(-1) \ imes (-1) \ imes (-1)\n]", "Calculating this stepwise:\n- First multiplication: ( (-1) \ imes (-1) = 1 ) (since the product of two negatives is positive)\n- Second multiplication: ( 1 \ imes (-1) = -1 )", "Thus,\n[\n(-1)^3 = -1\n]", "Now substitute back into the original function:\n[\nf(-1) = -1 + 2 = 1\n]", "Therefore, the evaluation yields:\n[\nf(-1) = 1\n]", "This result reflects both the proper order of operations (exponentiation before addition) and the fundamental rule that an odd power of (-1) remains (-1).
