To determine whether a function is linear or not, we need to verify that the equation is a polynomial of the first degree. This means that the function must have the form $latex f(x)=mx+b$ when reorganized, and the independent variable x must have an exponent of 1.

A linear function refers to when the dependent variable (usually expressed by 'y') changes by a constant amount as the independent variable (usually 'x') also changes by a constant amount. For example, the number of times the second hand on a clock ticks over time, is a linear function.

- In Sal's table, notice that every value of y equals 10 plus x^2 When x = 1, y = (1)² + 10 = 11 When x = 2, y = (2)² + 10 = 14 When x = 3, y = (3)²...
- well, you are not having a constant change in x and y. To go from x = 1 to x = 2, you add 1. to go from y = 1 to y = 4, you add 3. it's okay for no...
- Any equation in the format y=n(n stands for a number) or x=n will be linear.
- Linear equations can have negative values in them! For example: x y -2 -5 -1 -3 0 -1 1 1 This set of values is linear, because every time x increas...
- Just look at the value. He's going higher and higher in numbers, and the in the graph, its going from bottom to top. So that tells you it's increas...
- Yes, I would love to help I am not good at math but I can try and help you a little! What do you need help with? I will give you the most help I can!
- It means he is dividing the amount between the Y numbers by the amount between the X numbers. Example: X Y 14-11= 3 2-1=1 1 11 2 14 3/1= 3
17 de ene. de 2018 · Certainly students should be able to recognize that $y = mx + b$ defines a linear function; and they should be able to show a function is not linear by finding points on the graph with different slopes between them.
You know that a linear function satisfies the following property: $$f(a+b)=f(a)+f(b)$$ and you want to determine whether a particular function $g$ is linear, so you just check whether this property holds.
