College Algebra Formulas(Math 110) questions and
answers.
Pythagorean Equation - answer a2+b2=c2
Distance Formula - answer d = √[( x₂ - x₁)² + (y₂ - y₁)²]
Midpoint Formula - answer ((x₁+x₂)/2, (y₁+y₂)/2)
Equation Of A Circle - answer (x-h)²+(y-k)²=r²
Function - answer 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 - answer 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 - answer 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 - answer the set of a functions inputs, found on the
horizontal axis (x-axis).
Range - answer the set of a functions outputs, found on the vertical
axis (y-axis).
, Linear function - answer A function that can be written as
f(x)=mx+b where m and b are constants.
Constant function - answer The type of function where M=0
f(x)= b
Identity function - answer The type of function when m=1 and b=0
Horizontal lines - answer lines that are given by the equations of the
type y=b or f(x)=b
IE: y=b
Vertical lines - answer lines that are given by the equations of the
type x=a
They are not functions.
IE x=a
Slope - answer average rate of change
Parallel lines - answer Vertical lines and non-vertical lines with the
same slope and different y-intercept.
Perpendicular lines - answer if the product of a lines slope is -1 or if
one line is horizontal and the other is vertical.
A linear equation in one variable - answer If the equation can be
expressed in the form mx+b=0 where m and b are real numbers and
m is not equal to 0.
