What is a example of a linear function?

4x + y = 0

Step-by-step explanation: To determine whether the function 4x + y = 0 is linear, quadratic, or neither, let's first set the function equal to y by subtracting 4x from both sides to get y = -4x or y = -4x + 0.

Now, we can see y = -4x + 0 is in the form y = mx + b.

When a function is written in the form y = mx + b, we know that it's a linear function.

Another way to tell that it's a linear function is that the x in the function is raised to the first power.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
