f(x)=x
The expression given, f(x) = x, represents a linear function
The expression given, f(x) = x, represents a linear function. In this case, the output (f(x)) is equal to the input (x). In other words, the function returns the value of x as its output.
To visualize this function, you can plot the points on a graph. Since the function is linear, it will result in a straight line passing through the origin (0,0) with a slope of 1. This means that as x increases, f(x) will also increase at the same rate.
For example, if you substitute x = 1 into the function, f(1) = 1. If you substitute x = 2, f(2) = 2, and so on. The resulting points will lie on the line y = x.
It’s important to note that this is a simple example of a function, where the output is directly proportional to the input. In more complex functions, the relationship between the input and output can be more intricate.
