 TERM DEFINITION Monomial A number or the product of a number and one or more variables with whole-number exponents Coefficient A number in front of the variable in a monomial. Polynomial A sum or difference of monomials. Binomial A polynomial with two terms. Trinomial A polynomial with three terms Scientific Notation A number is written in scientific notation if it is written in the form N x 10n where n is an integer and Rational Expression A fraction in which both the numerator and denominator are polynomials Variable An unknown quantity usually denoted by a letter such as x. Quadratic Equation An equation that can be written in the form , where a, b, and c, are real numbers and . Complex Numbers A number that can be written in the form where a and b are real numbers and Linear Equation An equation whose graph is a line. x-intercept The x-intercept is the ordered pair (a, 0) and is the point where the graph intersects the x-axis y-intercept The y-intercept is the ordered pair (0, b) and is the point where the graph intersects the y-axis. Origin The point, (0, 0) where the x-axis and the y-axis intersect. Slope The slope of a line is the change in y divided by the change in x. Domain The set of all acceptable x-values for a function Range The set of all resulting y-values. Function A function is a set of ordered pairs (x, y) in which no two distinct ordered pairs have the same x-value. Parabola A parabola is the graph of a quadratic function. Vertex The vertex of a parabola is the ordered pair where the parabola intersects its axis of symmetry Axis of Symmetry A line passing through the vertex of a parabola that divides the parabola into two symmetrical parts. Asymptote An asymptote is a line that a graph approaches as the values of x approach positive or negative infinity. Exponential Function A function of the form where b > 0 and and x is any real number. Logarithmic Function A function of the form where b >0 and . Common Logarithm A logarithm with base 10 Natural Logarithm A logarithm with base e. Sequence A sequence is a function whose domain is the set of real numbers. Summation Notation A shorthand way to denote the sum of the first n terms of a sequence. Arithmetic Sequence A sequence in which each term, except the first is found by adding a constant to the preceding term. Arithmetic Means Arithmetic means are numbers inserted between the first and last terms of an arithmetic sequence. Geometric Sequence A sequence in which each term, except the first is found by multiplying the preceding term by a constant. Geometric Means Geometric means are numbers inserted between the first and last terms of a geometric sequence. Event A situation that has several outcomes Permutation A permutation is an ordered arrangement of items that occurs when no item is used more than once and the order of arrangement makes a difference. Combination A combination is an ordered arrangement of items that occurs when no item is used more than once and the order of arrangement does not make a difference.
