Unit 1 Flashcards
(30 cards)
A function that, when graphed, goes down from left to right.
Decreasing function
A function with a graph that is unbroken and consists of all points; connected with a solid line. Data where ALL REAL NUMBERS ARE ALLOWED IN THE DOMAIN.
Continuous function
The output variable of a function; the “y” value
Dependent variable
A function with a graph that consists of isolated, individual points; the graph is broke.
Discrete function
The set of all inputs; permissible values for “x”
Domain
A way to name a function using f(x) instead of “y”
F(x) notation
For each input (x), there is exactly one output (y); has a pattern; predicable
Function
A function that, when graphed, goes up from left to right
Increasing function
The input variable of a function;the “x” value
Independent variable
A function where the highest exponent is 1; forms a line when graphed
Linear function
A function where the highest exponent is 2; forms a parabola when graphed
Quadratic Function
The set of all outputs of a function; permissible values for “y”
Range
A pairing of a set of outputs with a set of inputs; situation where ordered pairs can be created.
Relation
Algebraically, table form, graphically, verbally. Also known as four corners
Representations
A letter that can be used to represent a number
Variable
Consists of numbers, variables, and operations. No equal sign
Expression
To solve
Evaluate
To work out to the point where you can’t work it out anymore
Simplify
A fraction that compares two qualities measured in different units
Rate
When the denominator is 1 and both parts of the fraction represent a unit of measurement
Unit rate
An open sentence that contains one of the following symbols
Inequality
The flip version of a fraction
Reciprocal
Same value or same solutions for all values of the variable
Equivalent
Two operations that undo each other
Inverse operation
