Not at all.
Y = x2 is a continuous function.
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
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.
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.
Cubic functions and linear functions are both polynomial functions, meaning they can be expressed using algebraic equations. Each type has a defined degree, with linear functions being of degree one and cubic functions being of degree three. Both types can exhibit similar behaviors, such as having real roots and being continuous and smooth. Additionally, they can both represent relationships between variables, but cubic functions can model more complex relationships due to their ability to have multiple turning points.
It can be continuous or discrete.
Linear equations are a tiny subset of functions. Linear equations are simple, continuous functions.
All linear equations are functions but not all functions are linear equations.

They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
Linear equations are always functions.

Yes, all polynomial functions are continuous.
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.
No. Not all functions are continuous. For example, the function f(x) = 1/x is undefined at x = 0.
