A function graph is a visual representation of the relationship between two variables, usually an x-axis (independent variable) and a y-axis (dependent variable). Each point on the graph represents a pair of values of the two variables, which satisfy the rules of a particular function.
A complex number is a number that consists of two parts: the real part and the imaginary part. The general form of a complex number is \(z=a+bi\), where a is the real part and b is the imaginary part, while i is an imaginary unit with the property \(i^2=-1\).
