Line 'Em Up!
This type of function graphs as a straight line.
Linear Function
This type of algebraic expression contains one or MORE terms with variables that have exponents, all being added or subtracted.
Polynomial
This kind of expression includes a square root, cube root, or higher root.
Radical Expression
This is the number being raised to a power in an exponential expression.
Base
This is the set of all possible x-values that a function can take.
Domain
This value tells you how steep a line is and how y changes when x increases by 1.
Slope
This algebra process rewrites a polynomial as a product of simpler expressions.
Factoring
This solving method involves isolating a squared term and taking the square root of both sides.
Square Root Method
This type of expression is the inverse of an exponential and tells you the power used to get a certain number.
Logarithm
This is the highest or lowest point on a parabola.
Vertex
This is the point where a graph touches or crosses the x-axis.
x-intercept
This describes how a function behaves as x approaches negative infinity and positive infinity.
End Behavior
After rewriting a radical expression using the smallest possible numbers inside the radical, you have the expression in this form.
Simplest Radical Form
This catchy acronym helps you remember how to find sine, cosine, and tangent.
SOHCAHTOA
This function has a V-shaped graph and always outputs a non-negative value.
Absolute Value
This form of a linear equation looks like Ax + By = C.
Standard Form
This is another word for a value of x that makes a polynomial equal zero.
Root / Zero / Solution (all acceptable)
This type of number includes i, where i² equals –1.
Imaginary Number
This formula helps you calculate a log using a different base on your calculator.
Change of Base Formula
This famous theorem uses a² + b² = c² to relate the sides of a right triangle.
Pythagorean Theorem
This is a vertical line that divides a parabola into two mirror images.
Axis of Symmetry
This is a quick method used to divide a polynomial by a binomial.
Synthetic Division
This expression, b² – 4ac, tells how many and what kind of solutions a quadratic has.
Discriminant
This trig ratio compares the opposite side to the adjacent side in a right triangle.
Tangent
In Probability, these are events where the outcome of one does not affect the outcome of the other.
