xaxis symmetry

replace the y with a y


yaxis symmetry

replace x with a x


symmetry with respect to the origin

replace the x and y with their reciprocals


Y intercept

where the graph crosses the y axis


Slope

Δy/Δx


General form for a line

Ax+By+c=0


Slope intercept form for a line

y=mx+b


Parellel lines

Slopes are equal; different y intercepts


Perpendicular lines

opposite signs on their slopes; Δy/Δx are negative reciprocals of each other


Function

A relation between two sets x and y is a of ordered pairs (x,y) is on the graph (x,y) in relation


Real Value function

f: x→y of a real variable x is a correpondence that assigns to each number of x exactly one number y


Domain

Range of all the xvalues


Range

Range of all the yvalues


Limit

Let f be a function defined on an open interval containing a # C, except possibly C itself. Let L be a real number. We say the limit as x approaches x f(x)=c exactly when for any E>0 there exists a d>0 such that 0<│xc│<d then the │f(x) L│< E.


Continuous function

A function is continuous if: f( c) is defined, limit as x approaches c exists, and the limit as x approaches c is equal to c


Intermediate Value Therom

If f is continuous on a closed interval [a,b] and k is any number between f (a) and f(b), then there must exists at least one number c in [a,b] with f ( c) =k.
