it's linear if for any x,y,k values: f(k*x + (1-k)*y) = k*f(x) + (1-k)*f(y)
or, an equivalent condition:
it's linear if for any k value: f(k) = k*f(1) + (1-k)*f(0) = f(0) + k*(f(1)-f(0))
examples:
f(x) = 7, x, 2x, 11-3x
non-linear in any other case. examples:
f(x)=x^2, sin(x), 1/x, ln x

Can nonlinear equations also be functions?
yes
How can you tell whether an equation is linear or nonlinear?
An equation is linear if it can be expressed in the form (y = mx + b), where (m) and (b) are constants, and the variables are raised only to the first power and multiplied by constants. In contrast, an equation is nonlinear if it includes variables raised to powers greater than one, products of variables, or functions such as exponentials, logarithms, or trigonometric functions. To determine the linearity, check for these characteristics in the equation. If any of these nonlinear elements are present, the equation is nonlinear.
What is a nonlinear scale?
A scale that is nonlinear. ~
What is nonlinear slope?
A nonlinear slope refers to a situation in which the relationship between two variables does not follow a straight line when graphed. Instead, the slope changes at different points along the curve, indicating that the rate of change varies. This can occur in various contexts, such as in economics, biology, or physics, where factors influence outcomes in a non-proportional manner. Nonlinear slopes are often analyzed using polynomial, exponential, or logarithmic functions.

What is nonlinear relations?
Nonlinear relations are mathematical relationships between variables where the graph of the relationship is not a straight line. This means that as one variable changes, the other variable does not change by a constant rate, resulting in a curved or non-linear shape on a graph. Examples of nonlinear relations include quadratic functions, exponential functions, and trigonometric functions.
What are some example problems that demonstrate the application of nonlinear functions?
Some example problems that demonstrate the application of nonlinear functions include calculating the trajectory of a projectile, modeling population growth in a biological system, and predicting the behavior of a complex electrical circuit. These problems involve relationships that do not follow a straight line and require the use of nonlinear functions to accurately describe and analyze the data.
What is nonlinear devices?
Nonlinear devices are components that do not follow a linear relationship between input and output. This means that their response is not proportional to the input signal. Examples include diodes, transistors, and nonlinear capacitors. Nonlinear devices are often used in electronic circuits to perform functions like signal processing and modulation.

Are the OP AMPS always linear?
not when they hit the power rail they aren't. or did you mean an opamp in a feedback circuit? the feedback circuit can give them a wide variety of transfer functions, some linear some nonlinear. nonlinear transfer functions include LOG, ANTILOG, GYRATION, SQRT, etc.
What is the difference between linear and nonlinear demand functions?
distinguish between linear and non linear demands funcions
What is a nonlinear scale?

How can the scaling parameters of nonlinear functions be optimized for improved performance?
The scaling parameters of nonlinear functions can be optimized for better performance by adjusting them to ensure that the function outputs are within a desired range. This can be done through techniques such as gradient descent or genetic algorithms to find the optimal values that minimize errors and improve the function's overall performance.
