What is the equation of an absolute value function?

The equation of an absolute value function is f(x) = |x|, where |x| denotes the absolute value of x, which is the distance of x from the origin on a number line.

How do you graph an absolute value equation?

To graph an absolute value equation, start by identifying the vertex of the absolute value function, which occurs at the point where the expression inside the absolute value bars equals zero. Plot this point on the graph. Then, choose several points on either side of the vertex and plug them into the absolute value equation to find the corresponding y-values. Plot these points and notice that the graph has a V-shaped or absolute value characteristic. Finally, draw a straight line connecting the points to complete the graph of the absolute value equation.

What does the vertex of an absolute value graph represent?

The vertex of an absolute value graph represents the minimum or maximum point of the graph, depending on whether the leading coefficient of the absolute value function is positive or negative. It is the point where the graph changes direction and either starts increasing or decreasing.

How do you find the x-intercepts of an absolute value equation?

To find the x-intercepts of an absolute value equation, set the expression inside the absolute value bars equal to zero and solve for x. This will give you the x-values where the absolute value equals zero, indicating the x-intercepts. Keep in mind that absolute value functions can have two x-intercepts if the expression inside the absolute value is negative and one x-intercept if it is positive or zero.

What is the significance of the y-intercept in an absolute value graph?

The y-intercept in an absolute value graph represents the point where the graph intersects the y-axis. It is significant because it shows the minimum value of the absolute value function, which is the point where the absolute value expression equals zero. This point serves as a reference for determining the behavior of the graph as it approaches or moves away from the y-axis.

How do you determine the domain and range of an absolute value function?

To determine the domain of an absolute value function, you consider the values that the input variable can take. Since the absolute value can accept any real number as an input, the domain is all real numbers (-?, ?). For the range, you consider the possible output values. The absolute value function always produces non-negative values, so the range is [0, ?).

What happens to the shape of an absolute value graph when the coefficient of x is changed?

Changing the coefficient of x in an absolute value graph affects the steepness or slope of the V-shaped graph. If the coefficient is greater than 1, the graph becomes narrower and steeper; if the coefficient is between 0 and 1, the graph becomes wider and shallower. The placement of the vertex remains the same, but the overall shape of the graph is altered based on the coefficient of x.

How do you graph an absolute value inequality?

To graph an absolute value inequality, first rewrite the inequality in standard form with the absolute value expression isolated on one side of the inequality. Next, consider the two cases for the absolute value expression (positive or negative) and solve for the variable in each case. Plot these solutions on a number line and shade the region that satisfies the inequality based on the desired inequality symbol (?, <, ?, >). Finally, indicate any points where the absolute value expression equals 0 by drawing open circles and the inequality symbol should be included.

How can you identify whether an equation or inequality is a horizontal or vertical shift of the basic absolute value graph?

To identify whether an equation or inequality is a horizontal or vertical shift of the basic absolute value graph, you would look at how the equation is modified. If the equation involves adding or subtracting a constant to the absolute value function, it indicates a vertical shift. On the other hand, if the equation involves replacing the variable with a variable plus or minus a constant, it indicates a horizontal shift. By recognizing these patterns in the equation, you can determine whether it represents a horizontal or vertical shift of the basic absolute value graph.

How do you solve absolute value equations algebraically?

To solve absolute value equations algebraically, isolate the absolute value term on one side of the equation and consider two cases: when the expression inside the absolute value bars is positive and when it is negative. Remove the absolute value bars and set up two equations, one with the expression on the right side equal to the absolute value, and another with the expression on the right side equal to its negative. Solve both equations separately to find the possible solutions for the variable.
