Pythagorean ( correct a2+b2=
Equation answers ) c2
Distance ( correct d = √[( x₂ - x₁)² + (y₂ -
Formula answers ) y₁)²]
Midpoint ( correct ((x₁+x₂)/2,
Formula answers ) (y₁+y₂)/2)
Equation Of A Circle ( correct answers ) (x-h)²+(y-k)²=r²
Function ( correct answers ) A correspondence between a first set,
called the domain, and a second set, called the range, such that each
member of the domain corresponds to exactly one member of the range.
Relation ( correct answers ) A correspondence between a first set,
called the domain, and a second set, called the range, such that each
member of the domain corresponds to at least one member of the
range.
The Vertical Line Test ( correct answers ) If it is possible for a vertical line to
cross a graph more than once, then the graph IS NOT the graph of a function.
Domain ( correct answers ) the set of a functions inputs, found on the
horizontal axis (x-axis).
Range ( correct answers ) the set of a functions outputs, found on the
vertical axis (y-axis).
Linear function ( correct answers ) A function that can be written as
f(x)=mx+b where m and b are constants.
Constant function ( correct answers ) The type of function where
M=0 f(x)= b
Identity function ( correct answers ) The type of function
Horizontal lines
when m=1 and b=0 ( correct answers ) lines that are given by the equations
type y=b or of the
f(x)=b IE: y=b
