How would you know if a function is linear or non-linear just by looking at a input-output table?
I don't know that you can do it just by looking at one. (At least, I'm not clever enough with arithmetic to do that.) But it's possible to do it using some simple aritmetic. Here's an input-output table.
5 38
6 45
7 52
8 59
The first thing I notice is that the numbers in the left-hand column are evenly spaced; the difference between any two of them is just one. The differences between all of the numbers in the right-hand column are also all the same, seven. So this input-output table represents a linear function.
In case you're working in a slightly more advanced situation here's another example:
3 11
7 23
9 29
13 41
In this case the left-hand column numbers are not evenly spaced and I can't just look at the differences between the numbers on the left. However, there's a slightly more advanced technique that I can apply.
( 23 - 11 ) / ( 7 - 3 ) = 12 / 4 = 3
( 29 - 23 ) / ( 9 - 7 ) = 6 / 2 = 3
( 41 - 29 ) / ( 13 - 9 ) = 12 / 4 = 3
The three slopes are the same. Therefore, the input-output table represents a linear function.
What else can I help you with?
How can you tell by looking at the graph of a function that it is nonlinear?
A linear function would be represented by a straight line graph, so if it's not a straight line, it's nonlinear
How can you tell by looking only at the equation of a function with no graph that it is nonlinear?
To be linear, there should only be constants, and variables with constant coefficients. No powers of variables, or numbers raised to the power of a variable, or any other nonlinear function such as log, ln, sin, cos, tan, cosh, etc.
What is the use of a differential?
Differentials can be used to approximate a nonlinear function as a linear function. They can be used as a "factory" to quickly find partial derivatives. They can be used to test if a function is smooth.

Is the following function linear or nonlinear If linear, state the rate of change?
o function is given. However, if linear , then the rate of change is the same as the steepness of the graph line.
Is the perimeter of a square a linear or nonlinear function of the length of one of its sides?
linear, if side is x then perimeter is 4x

What is linear and nonlinear?
A linear or non linear function is a function that either creates a straight line or a crooked line when graphed. These functions are usually represented on a table under the headings x and y.
