Math 2 HN

Rx-axis (x,y)

2 Keep x and negate the y to represent a reflection in the x-axis. (x,-y)

Ry-axis (x,y)

Keep the y and negate the x to represent a reflection in the y-axis. (−x,y)

Ry=x (x,y)

Switch the x and y coordinates to represent a reflection over the line y=x. (y,x)

Ry=-x (x,y)

Switch the x and y then negate the both coordinates to represent a reflection over the line y=-x. (-y,-x)

Graphing Square Root Equations

A method used to represent equations of the form y = √x, which produces a graph that is half of a parabola, opening to the right.

Square-Double-Square or Squaring a Binomial Formula

A formula used to simplify expressions of the form (a+b)(a-b) = a² +- 2ab + b², which is useful in algebra for factoring and solving quadratic equations.

Solving Radical Equation Steps

The process of isolating the radical on one side of the equation, squaring both sides to eliminate the radical, and then solving the resulting equation for the variable. This may require checking for extraneous solutions.

Exponent Properties

A set of rules that describe how to manipulate and simplify expressions involving exponents, including multiplication, division, and power of a power rules. These properties are essential for simplifying algebraic expressions and solving equations.

Midpoint Formula

The Midpoint Formula is used to find the midpoint between two points in a coordinate plane, defined as M = ((x₁ + x₂)/2, (y₁ + y₂)/2). This formula is essential in geometry for determining the center point of a segment.
