Linear functions

Functions that can be represented by a straight line on a graph.

Single variable equations

Equations that contain only one variable.

Systems of linear equations

A set of equations with the same variables that are solved together.

Absolute value

A measure of a number's distance from zero on the number line, always non-negative.

Manipulating polynomials

The process of adding, subtracting, multiplying, or dividing polynomial expressions.

Quadratic equations

Equations of the form ax^2 + bx + c = 0, where a, b, and c are constants.

Dividing polynomials

The process of dividing one polynomial by another polynomial.

Exponential functions

Functions of the form f(x) = a * b^x, where a is a constant, b is the base, and x is the exponent.

Function notation

A way to represent functions using symbols, commonly f(x) for the function f at the value x.

Solving exponential equations

Finding the value of the variable in equations where the variable is in the exponent.

Systems of equations with nonlinear equations

A set of equations that includes at least one nonlinear equation.

Ratios and proportions

Comparative relationships between two quantities expressed as a fraction or ratio.

Scatterplots and graphs

Visual representation of data points on a coordinate plane.

Categorical data and probabilities

Data divided into categories, with probabilities representing likelihood of outcomes.

Experimental interpretation

The process of analyzing data from experiments to draw conclusions.

Mean, median, mode, standard deviation

Measures of central tendency (mean, median, mode) and variability (standard deviation) in statistics.

Coordinate geometry - lines and slopes

Study of geometric figures using a coordinate system to find properties like slope.

Coordinate geometry - nonlinear functions

Study of geometric figures defined by nonlinear equations in the coordinate plane.

Geometry - circles

The study of properties and relations of circles.

Geometry - lines and angles

The study of straight lines, angles, and their relationships.

Geometry - solid geometry

The study of three-dimensional geometric figures.

Geometry - triangles and polygons

The study of two-dimensional shapes like triangles and polygons.

Trigonometry

The branch of mathematics dealing with the relationships between the angles and sides of triangles.

Complex numbers

Numbers that include a real part and an imaginary part, expressed in the form a + bi.
