How do you find a linear function?

By finding something who's behavior is represented by a linear function and graphing it.


How can you tell a linear function from an equation?

An equation is a statement that two things are equal. A function is a rule or process that gives you a value if you give it something in its domain (the set of things on which it is defined) as an argument. Functions on numbers that are defined by a rule can usually be expressed by an equation. A linear function is one that can be defined by a linear equation.


Write a rule that is an example of a non-linear function when b is 49 a is 7 and a is a function of b?

Below is a rule that is an example of a non-linear function when b is 49, a is 7 and a is a function of b: a = square root of b 7 = square root 49 7=7


How do you graph linear functions?

A linear function is called "linear" because it represents a straight line. To graph a linear function, find two points that satisify that function, plot them, and then draw a straight line between them.


Does the rule y equals 4x4x represent a linear or exponential function explain?

yes


Linear function increasing?

A linear function is increasing if it has a positive slope. To find this easily, put the function into the form y=mx+b. If m is positive, the function is increasing. If m is negative, it is decreasing.


Is linear function the same as linear equations?

No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.


What is the end behavior of a linear function?

Assuming the domain is unbounded, the linear function continues to be a linear function to its end.


What is a slope in mathematics?

It's the gradient, or the steepness, of a linear function. It is represented by 'm' in the linear formula y=mx+b. To find the slope of a line, pick to points. The formula is (y2-y1)/(x2-x1). See the related link "Picture of a Linear Function for a picture of a linear function.


Is an exponential function linear?

No. An exponential function is not linear. A very easy way to understand what is and what is not a linear function is in the word, "linear function." A linear function, when graphed, must form a straight line.P.S. The basic formula for any linear function is y=mx+b. No matter what number you put in for the m and b variables, you will always make a linear function.


Would it be easier to find the rule for a function table with 3 pairs of numbers or 4 pairs of numbers?

If it's a linear function, 3 should do, but 4 will give an extra check on you work. If the function is quadratic exponential, etc. then at least 4 pairs should be used.
