Family of Curves
A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These families appear commonly in the solution of differential equations. When a constant of integration is added, it is normally modified algebraically until it no longer replicates a plain linear transformation. The order of a differential equation depends on how many uncertain variables appear in the corresponding curve. The order of the differential equation acquired is two if two unknown variables exist in an equation belonging to this family.
XZ Plane
In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are real numbers and a is the horizontal coordinate and b is the vertical coordinate. This type of plane is called two-dimensional and it contains two perpendicular axes, the horizontal axis, and the vertical axis.
Euclidean Geometry
Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) geometry was introduced by the Greek mathematician Euclid, and that is why it is called Euclidean geometry. Euclid explained this in his book named 'elements'. Euclid's method in Euclidean geometry involves handling a small group of innately captivate axioms and incorporating many of these other propositions. The elements written by Euclid are the fundamentals for the study of geometry from a modern mathematical perspective. Elements comprise Euclidean theories, postulates, axioms, construction, and mathematical proofs of propositions.
Lines and Angles
In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.
![### Consider the following:
\[ y = |3 - x| \]
Sketch the graph of the equation.
#### Explanation of the Graphs
The task requires sketching the graph of the equation \( y = |3 - x| \).
1. **Graph 1**: The graph shows the function \( y = |3 - x| \), which is a V-shaped curve. The vertex of the curve is located at \( (3, 0) \). The graph is decreasing on the left side of the vertex and increasing on the right side. It exhibits absolute symmetry around the vertical line passing through \( x = 3 \).
2. **Graph 2**: Similarly, this graph also demonstrates the function \( y = |3 - x| \). The vertex at \( (3, 0) \) is evident, and the V-shape is symmetrical around the line \( x = 3 \).
3. **Graph 3**: This graph shows the same function with its vertex positioned at \( (3, 0) \). The symmetry and V-shape are consistent, and the function opens upwards extending from the vertex.
4. **Graph 4**: This graph depicts the \( y = |3 - x| \) function, maintaining the same properties as the previous graphs. The vertex at \( (3, 0) \) shows that the graph is the V-shaped curve typical of absolute value functions.
Each graph accurately represents the behavior of the absolute value function, showcasing the characteristic V-shape centered at the specific point where the absolute expression within the absolute value becomes zero.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc550f2c8-5f01-4988-ace5-8dc585de8201%2Fb8fb0733-020a-4efe-8143-a89b9b32c9ea%2Fq9oup6t.jpeg&w=3840&q=75)
