The function f(x) = x^3 – 2x^2 is a polynomial function that involves raising x to the power of 3 and subtracting 2 times x squared. One interesting aspect of this function is evaluating it at complex numbers, such as f(i). This process involves substituting the complex number i into the function and calculating the result. In this article, we will delve into the complex truth behind evaluating f(i) in the function f(x) = x^3 – 2x^2.
Unveiling the Complex Truth
When we talk about evaluating f(i) in the function f(x) = x^3 – 2x^2, we are essentially substituting the complex number i into the function. In the context of complex numbers, i represents the imaginary unit, which is defined as the square root of -1. Therefore, f(i) = i^3 – 2i^2. Simplifying this expression, we get f(i) = -i – 2(-1) = -i + 2.
This result, f(i) = -i + 2, showcases the complex nature of evaluating functions at complex numbers. The imaginary unit i introduces a new dimension to the calculation, leading to a complex number as the output. In this case, the result f(i) is a complex number with a real part of 2 and an imaginary part of -1. This highlights the intricacies involved in dealing with complex numbers in mathematical computations.
