# How do you find the left and right behavior of a graph?

|Use the Leading Coefficient Test to determine the end behavior of the graph of the polynomial function f(x)=−x3+5x . Solution: Because the degree is odd and the leading coefficient is negative, the graph rises to the left and falls to the right as shown in the figure.

Use the Leading Coefficient Test to **determine** the **end behavior** of the graph of the polynomial function f(x)=−x3+5x . Solution: Because the degree is odd and the leading coefficient is negative, the graph rises to the **left** and falls to the **right** as shown in the figure.

Additionally, how do you find the Y intercept? To **find** the **y intercept** using the equation of the line, plug in 0 for the x variable and solve for **y**. If the equation is written in the slope-**intercept** form, plug in the slope and the x and **y** coordinates for a point on the line to solve for **y**.

Considering this, what is end behavior of a graph?

**End Behavior** of a Function. 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 is an even multiplicity?

If the **multiplicity** is odd, the graph will cross the x-axis at that zero. That is, it will change sides, or be on opposite sides of the x-axis. If the **multiplicity** is **even**, the graph will touch the x-axis at that zero. That is, it will stay on the same side of the axis.

### What is right end behavior?

In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).

### How do you find Asymptotes?

The horizontal asymptote of a rational function can be determined by looking at the degrees of the numerator and denominator. Degree of numerator is less than degree of denominator: horizontal asymptote at y = 0. Degree of numerator is greater than degree of denominator by one: no horizontal asymptote; slant asymptote.

### How do you determine end behavior?

Then, the coefficient of the lead term will determine the behavior of the polynomial. If the variable (let’s say X) is negative, then the X in the highest degree term creates a negative. We then multiply the coefficient of the lead term with a negative to determine the end behavior.

### What does multiplicity mean in algebra?

In mathematics, the multiplicity of a member of a multiset is the number of times it appears in the multiset. For example, the number of times a given polynomial equation has a root at a given point is the multiplicity of that root.

### What is the sign of the leading coefficient of F?

If the leading coefficient is positive the function will extend to + ∞; whereas if the leading coefficient is negative, it will extend to – ∞. Polynomial Functions. Degree of the polynomial Leading coefficient + – Even f(x) → ∞ as x → ±∞ f(x) → -∞ as x → ±∞ Odd f(x) →-∞ as x → -∞ f(x) → ∞ as x → ∞ f(x) → ∞ as x → -∞ f(x) → -∞ as x → ∞

### How do you identify the domain and range of a function?

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
