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.

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


What is a nonlinear in math?

when you represent any equation in a graph it is said to be linear.Accordin to me , not having a definite equation , is said to be non-linear.


What is the equation of a nonlinear graph if a is greater than 5?

There are infinitely many options. The equation could be a polynomial of degree greater than 1, or it could be a power function, a log function or any combination of these with trig functions. The problem is exacerbated by the fact that there is no clue in the question as to what a stands for.

Without using a graph how can you tell if an equation is a function or relation?

Verticle line test man. If it intersects two points it is its not a function. if it hits one point it is a function. and im currently looking up to see how it is a equation...

When you are given a graph how can you come up with a rational function equation?

You cannot, necessarily. Given a graph of the tan function, you could not.


How do you determine if a relation represents a function?

If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!
