Question

What is the defining equation of f (x) = x

Answer 1

Step-by-step explanation:

f(x) is the value of the function. m is the slope of the line. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane. x is the value of the x-coordinate.

Answer 2

To find: The defining equation of $f(x)=x$

Step-by-step explanation:

• A function is a statement, rule, or legislation that establishes a link between one variable (the dependent variable) and another variable (the independent variable). In mathematics, functions are everywhere, and they're crucial for articulating physical links in the sciences.

• This relationship is often denoted by the notation y = f(x), which means $f(x)$," and $y$ and $x$ is coupled in such a way that there is a unique value $y$ for each $x$.
• That is, for the same $x$, $f(x)$ cannot have more than one value. A function, in set theory terms, connects an element $f(x)$ to an element  in another set. The domain of the function is the set of values $x$, and the range of the function is the set of values $f(x)$ generated by the values in the domain.
