## What are parent functions in algebra?

A parent function is the simplest function that still satisfies the definition of a certain type of function. For example, when we think of the linear functions which make up a family of functions, the parent function would be y = x. This is the simplest linear function.

**What is end behavior algebra?**

The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph.

**What are the characteristics of a parent function?**

What are some characteristics of the basic parent functions? (Linear…

- Odd. End behavior go in different directions. If a function is positive, the left side of the graph will point down and the right side will point up (increasing from left to right).
- Straight line. Constant. Has a slope.

## How would you describe the end behavior of the graph?

The end behavior of a graph is defined as what is going on at the ends of each graph. As the function approaches positive or negative infinity, the leading term determines what the graph looks like as it moves towards infinity.

### How do you find the end behavior asymptote?

Step 1: Look at the degrees of the numerator and denominator. If the degree of the denominator is larger than the degree of the numerator, there is a horizontal asymptote of y=0 , which is the end behavior of the function. The degree of the numerator is 4, and the degree of the denominator is 3.

**What are the 12 parent functions?**

- cosine function. f(x) = cos x.

**What are parent functions?**

y=x (linear function)

## What are all the parent functions?

Constant Functions. Constant functions are functions that are defined by their respective constant,c.

### What is an example of end behavior?

Since the leading coefficient of this odd-degree polynomial is positive, then its end-behavior is going to mimic that of a positive cubic. Therefore, the end-behavior for this polynomial will be: “Down” on the left and “up” on the right.

**What is an example of a parent function?**

Distance is a linear function of time and speed; specifically d = r t .
