Linear functions
This type of sequence adds or subtracts a constant value to get the next term.
Arithmetic Sequence
This type of number cannot be written as a simple fraction and has decimals that go on forever without repeating (like pie).
What is an Irrational Number?
This is the "U-shaped" curve created by a quadratic function.
What is a Parabola?
In the equation y = a(b)^x, if b is greater than 1, the function represents this.
What is Exponential Growth?
This measure of center is found by adding all numbers and dividing by the total count.
What is the Mean?
In an inequality graph, you use this type of line when the symbol is < or >
What is a dashed (or dotted) line?
This is the simplified version of the radical expression sqrt 25
What is 5
These are the two points where the parabola crosses the x-axis (also called roots or zeros).
What are the X-intercepts?
This is the horizontal line that an exponential graph approaches but never actually touches.
What is an Asymptote?
In a box plot, this value represents the "middle" of the data set.
What is the Median?
This is the starting value or the "initial value" of a linear function on a graph.
What is the y-intercept?
When adding radicals like 3 sqrt2+ 5 sqrt 2, you add these numbers together.
What are the coefficients? (Result is 8 sqrt 2)
This vertical line passes through the vertex and divides the parabola into two matching halves
What is the Axis of Symmetry?
This term describes the amount of time it takes for a substance to decrease by exactly half.
What is Half-Life?
This statistical value (r) tells you how strong the relationship is between two variables.
What is the Correlation Coefficient?
To find the solution to a System of Inequalities, you look for this specific area on the graph.
What is the overlapping shaded region?
To simplify sqrt 50, you must find the largest of these hidden inside 50.
What is a Perfect Square? (Specifically 25; result is 5 sqrt 2)
In the Diamond Method, you are looking for two numbers that multiply to give you a c and add to give you this.
What is b (or the middle coefficient)?
This type of interest is calculated on both the initial principal and the accumulated interest from previous periods.
What is Compound Interest?
This is the formula used to find the exact middle point between two coordinates
(x1, y1) and (x2, y2).
What is the Midpoint Formula?
Use this formula to find any term (an) in an arithmetic sequence without listing them all out.
What is the Explicit Formula? [a_n = a_1 + (n-1)d]
True or False: The sum of a rational number and an irrational number is always irrational.
What is True?
Use this property to solve (x - 5)(x + 2) = 0 by setting each factor equal to zero.
What is the Zero Product Property?
In exponential decay, the "b" value (growth/decay factor) must be between these two numbers.
What are 0 and 1?
This type of data plot uses a "5 Number Summary" (Min, Q1, Median, Q3, Max)
What is a Box Plot (or Box-and-Whisker Plot)?
