They are called linear functions because when graphed in the coordinate plane, they produce a straight line. A linear function can be recognized because none of the variables have an exponent larger than 1. The example given is also a monomial function, meaning that it only has one term: 3x...
Instead of a notation such as y=f(x)y=f(x), could we use the same symbol for the output as for the function, such as y=y(x)y=y(x), meaning “y is a function of x?” Yes, this is often done, especially in applied subjects that use higher math, such as physics and enginee...
these notations are the oldest in the world in any aspect of the life, in mathematics they are used to define the relations that exist in an operation, since it can indicate or to point according to its symbolism as the operation is directed, quantities...
In the twentieth century, when computer coding started becoming a thing, coders adopted the mathematical meaning to refer to inputs to their coding. In our mathematical context, the "argument" is the independent variable (the one for which you pick a value, usually being thex-value) and the...

The function notation is denoted as f(x) which means that the independent variable of the function is x. To write the function in function notation, we only have to change y to f(x). This would also mean that we have to solve for y in terms of x first....
If there is only one variable, then it is impossible to swap the x's and y's, meaning there is no inverse. How do you graph the inverse of a function? There are two methods. In the first method, first find the inverse algebraically, then make a table of values to help draw the ...
R is Transitive(可传递) meaning for all x, y, z \in A, if xRy and yRz, then xRz. e.g. "=" is an equivalence relation on \mathbb{N}. 2.5 Equivalence Class 等价类 Given an equivalence relation R over a set A, for any x \in A, the equivalence class of x in the set[x]_...
for f, g in the set BC(I) of bounded, continuous, complex-valued functions on I (here z* denotes the complex conjugate of the complex number z; for real numbers r we have r*=r). As a matter of convenience and simplicity of notation we may consider the integral in Eqn. (2) to ...
According to Math Boys, the word absolute comes from a variant of the word absolve and has a meaning close to free from conditions or restriction. The term, as it relates to mathematics, was first found in 1950 inthe elements of analytical geometry; comprehending the doctrine of the conic se...
