What is X 1 on a graph?
x=1. Since x=1 is a vertical line, there is no y-intercept and the slope is undefined.
What is the vertex of y =-| X 1?
(1,0)
In this case, the vertex for y=−|x−1| y = – | x – 1 | is (1,0) . To find the x x coordinate of the vertex, set the inside of the absolute value x−1 x – 1 equal to 0 0 . In this case, x−1=0 x – 1 = 0 .
How do you write absolute value on a graph?
f (x) = – | x + 2| + 3 In general, the graph of the absolute value function f (x) = a| x – h| + k is a “V” with vertex (h, k), slope m = a on the right side of the vertex (x > h) and slope m = – a on the left side of the vertex (x < h).
What does absolute value of X mean?
Definitions: The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.
How do you find the vertex?
We find the vertex of a quadratic equation with the following steps:
- Get the equation in the form y = ax2 + bx + c.
- Calculate -b / 2a. This is the x-coordinate of the vertex.
- To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
What is absolute value of x2?
According to this definition the |x| is always greater than or equal to zero for all real numbers. |x + 2| ≥ 0 and |x + 2| < 0. This is because, by definition, the absolute value of x + 2 can be either x + 2 or − (x + 2).
What’s the absolute value of 1?
Some complex numbers have absolute value 1. Of course, 1 is the absolute value of both 1 and –1, but it’s also the absolute value of both i and –i since they’re both one unit away from 0 on the imaginary axis. The unit circle is the circle of radius 1 centered at 0.
What is the slope of y =- 1?
Using the slope-intercept form, the slope is 0 .
What is a vertex on a graph?
“Vertex” is a synonym for a node of a graph, i.e., one of the points on which the graph is defined and which may be connected by graph edges. The terms “point,” “junction,” and 0-simplex are also used (Harary 1994; Skiena 1990, p. 80).
How do I graph a quadratic equation?

- Write the quadratic equation with. on one side.
- Determine whether the parabola opens upward or downward.
- Find the axis of symmetry.
- Find the vertex.
- Find the y-intercept.
- Find the x-intercepts.
- Graph the parabola.
