Question

1. let (c = i - 1) and (z=(i - 1)=-1 + i). then what about (c) 4) what part represents the x - axis for complex graphs?

Explanation:

Step1: Recall complex - number graph concept

In a complex - number graph (Argand diagram), a complex number is written in the form \(z=a + bi\), where \(a\) is the real part and \(b\) is the imaginary part.

Step2: Identify the axis

The \(x\) - axis of a complex graph represents the real part of the complex number.

Answer:

The real part of the complex number.
