How are linear equations and functions alike?
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
Can a linear function be continuous but not have a domain and range of all real numbers?
Yes, a linear function can be continuous but not have a domain and range of all real numbers. For example, the function ( f(x) = 2x + 3 ) is continuous, but if it is defined only for ( x \geq 0 ), its domain is limited to non-negative real numbers. Consequently, the range will also be restricted to values greater than or equal to 3, demonstrating that linear functions can have restricted domains and ranges while remaining continuous.
Can all functions be discrete or continuous?
No. There are many common functions which are not discrete but the are not continuous everywhere. For example, 1/x is not continuous at x = 0 (it is not even defined there. Then there are curves with step jumps.
Is a linear graph considered to be a continuous graph?
It can be continuous or discrete.
How are linear equations similar or different from functions?
A linear equation is a specific type of function that represents a straight line on a graph. While all linear equations are functions, not all functions are linear equations. Functions can take many forms, including non-linear ones that do not result in a straight line on a graph. Linear equations, on the other hand, follow a specific form (y = mx + b) where the x variable has a coefficient and the equation represents a straight line.
What similarities and differences do you see between the function and linear equations?
Linear equations are a tiny subset of functions. Linear equations are simple, continuous functions.
Are linear equations and functions different?
All linear equations are functions but not all functions are linear equations.

Are all linear equations functions Is there an instance when a linear equation is not a function?
Linear equations are always functions.
Are all polynomial funcions continuous?
Yes, all polynomial functions are continuous.
Can a linear function be continuous but not have a domain and range of all real numbers?
Yes, a linear function can be continuous but not have a domain and range of all real numbers. For example, the function ( f(x) = 2x + 3 ) is continuous, but if it is defined only for ( x \geq 0 ), its domain is limited to non-negative real numbers. Consequently, the range will also be restricted to values greater than or equal to 3, demonstrating that linear functions can have restricted domains and ranges while remaining continuous.
What are the similarities between linear relationships and quadratic relationships?
All linear equations of the form y = mx + b, where m and b are real-valued constants, are functions. A linear equation of the form x = a, where a is a constant is not a function. Functions must be one-to-one. That means each x-value is paired with exactly one y-value.
Are all functions continuous?
No. Not all functions are continuous. For example, the function f(x) = 1/x is undefined at x = 0.
