Last updated: June 11, 2021 | Author: Clarence Gildersleeve

## How do you know if a graph is mirrored about the x-axis?

**How to: Given a function, reflect the graph both vertically and horizontally.**

**Consideration**. The new

**graph**is a

**Consideration**of the original

**graph**about the

**x**

**axis**.

**horizontal reflection**.

## What is the rule for a reflection about the x-axis?

That **Rule for a reflection over x** **axis** is (**x**,y)→(**x**,−y) .

## How to tell if a function is mirrored about the y-axis?

**Consideration** on the **j****axis**: **j** = f ( − x ) **j** = f(-x) **j**=f(−x) In addition to translations, another type of transformation of **function** is called **Consideration**. **if** a **Consideration** it’s about them **j****axis**then the dots on the right side of the **j****axis** gets to the right side of the **j****axis**and vice versa.

## What does reflection at x =- 2 mean?

If you **reflect** one point **above** the line y = **x**the **x**-coordinate and the y-coordinate swap places. or. **Think** every other line. Notice that each point of the original figure and its image is the same distance from the line from **Consideration** (**x** = **2** in this example).

## What happens when you think about YX?

When **you reflect** one point **above** the **j**-Axis that **j**-Coordinate remains the same, but the **x**-Coordinate transformed into its opposite (its sign is changed). the **j**-axis is the point (-**x**,**j**). **Consider it** the **j** = **x**: When **you reflect** one point **above** the line **j** = **x**the **x**– coordinate and **j**– Coordinate relocation.

## How do you reflect on X?

The rule to think about **Above** the **X** axis is to negate the value of the y-coordinate of each point, but leave the **x**-value same. For example, if point P with coordinates (5,4) is reflected **above** the **X** Axis and mapped to point P’, the coordinates of P’ are (5,-4).

## What is the rule for YX?

The line **j**=**x**would appear when graphed on a graphing calculator as a straight line intersecting through the origin with a slope of 1. For example: For triangle ABC with coordinate points A(3,3), B(2,1) and C( 6,2), apply a reflection over the line **j**=**x**. Following the notation, we would swap them **x**-Value and the **j**-Value.

## What is the reflection rule?

A transformation using a line acting as a mirror with an original figure (archetype) **reflected** in the line for creating a new figure (picture) is called a **Consideration**.

## How do you reflect a shape?

reflecting on a **shape** means easy to **tip** it over a **mirror** Line. Every point in the **shape** is moved to the other side **mirror** line, but stays the same distance from the line. That **reflected** The image is now pointing in the opposite direction to the original object.

## How do you find reflection?

performance **reflections**

The line of **Consideration** is usually given in the form y = mx + by = mx + by=mx+by, equals, m, x, plus, b. How to draw the line of **Consideration**? Every point in the original figure has the same perpendicular distance from the line from **Consideration** as the corresponding point in the image.

## How do you enlarge a shape?

to **enlarge a shape**, an expansion center is required. When a **shape** is magnified from a magnification center, the distances from the center to each point are multiplied by the scaling factor.

## How do you like the area?

## What is the area formula?

perimeter, area and volume

Table 2. area formulas |
||
---|---|---|

shape | formula |
variables |

square | A=s2 | s is the side length of the square. |

rectangle | A=LW | L and W are the side lengths of the rectangle (length and width). |

triangle | A=12BH | b and h are base and height |

## What is perimeter and area?

About transcript. **Scope** is the distance around the outside of a shape. **area** measures the space within a shape.

## What is the perimeter formula?

That **formula** for the **Scope** of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the area covered by the shape.

## How do you find the perimeter with the area?

The relationship between **area** and **Scope** of a square it is **Scope** is 4 times the square root of **area**. to **receive** the **Scope** of the **area** for a square, multiply the square root of **area** times 4 **Scope** is always measured in linear units derived from the **areas** square units.

## What is a scope in math?

**Scope** is the distance around the edge of a shape.

## How do you find the perimeter given the area?

**Scope** a rectangle

**Scope**and

**area**a rectangle. That

**area**of a rectangle, a = length * width, while the

**Scope**is p = (2 * length) + (2 * width)

**area**Formula. 36 = 4 * m.

**Scope**Formula.

## How do you find perimeter using area and width?

That **Scope** P of a rectangle is given by the formula P=2l+2w, where l is the length and w is the **Broad** of the rectangle. That **area** A of a rectangle is given by the formula A=lw, where l is the length and w is the **Broad**.
