## How do you find the end behavior of a function?

To determine its end behavior, look at the leading term of the polynomial function. Because the power of the leading term is the highest, that term will grow significantly faster than the other terms as x gets very large or very small, so its behavior will dominate the graph.

**How do you know if a problem is an exponential function?**

In an exponential function, the independent variable, or x-value, is the exponent, while the base is a constant. For example, y = 2x would be an exponential function. You can see that this conforms to the basic pattern of a function, where you plug in some value of x and get out some value of y.

### What is the behavior of exponential function?

For exponential functions, we see that the end behavior tends to infinity really fast. The larger the growth factor, which is the base of the exponential function, the quicker we get to infinity. We also see that for very small values of our input, our variable, the graph is close to 0.

**What are the characteristics of exponential functions?**

Here are some properties of the exponential function when the base is greater than 1.

- The graph passes through the point (0,1)
- The domain is all real numbers.
- The range is y>0.
- The graph is increasing.
- The graph is asymptotic to the x-axis as x approaches negative infinity.

## What is end behavior of a polynomial?

The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity. So, the sign of the leading coefficient is sufficient to predict the end behavior of the function.

**What are some of the characteristics of exponential decay functions?**

Properties of Exponential Decay Functions The function y=f(x)=aekx function represents decay if k<0 and a>0. The function is a decreasing function; y decreases as x increases. Range: If a>0, the range is { positive real numbers } The graph is always above the x axis.

### What is the formula for end behavior?

1 End Behavior for linear and Quadratic Functions. A linear function like f(x) = 2x−3 or a quadratic function f(x) = x2 +5x+3 are pretty generic.

**What determines end behavior?**

End Behavior refers to the behavior of a graph as it approaches either negative infinity, or positive infinity . It is determined by a polynomial function s degree and leading coefficient.

## What determines the end behavior of a function?

The end behavior of a function is the behavior of the graph of the function f (x) as x approaches positive infinity or negative infinity. This is determined by the degree and the leading coefficient of a polynomial function. For example in case of y = f (x) = 1 x, as x → ±∞, f (x) → 0.

**How do you determine the end behavior of a graph?**

The degree and the leading coefficient of a polynomial function determine the end behavior of the graph. The appearance of a graph as it is followed farther and farther in either direction. For polynomials, the end behavior is indicated by drawing the positions of the arms of the graph, which may be pointed up or down.
