 what is an expresstion? Numbers and varibles with operations. does not contain an = sign. what is an Equastion? two diffrent expresstions that have an = sign. what is the Addition property? A=B if->a+b=b+c what is the Multiplication property? A=B if->A*C=B*C what is a Linear equastion? an equation that can be written as A*X+B=0. Where A and B are real numbers. A can not equal 0 what is a Quadratic equastion? an equastion that can be written in the standard form AX^2+BX+C=0.Where A,B,C, are real numbers. A can not equal 0. How is a Quadratic equastion solved? By using factoring or by the square root Property. what is the Square Root property? If U^2=K then U=+-(square root of K) what is the quadratic equastion? x= -B+-(Square root of: (B^2-4A*C)/2A) what is Slope Intercept form? Y=MX+B How would you enter an equastion into the calculator? You MUST put it in Slope Intercept form. What is the midpoint formula? ((x1+x2)/2 , (y1+y2)/2) What is a circle? A circle is the set of points on a plane that all have a fixed distance "R" from a Center (H,K) What is the equastion of a circle? The center (H,K) and the radius (R) the STANDARD FORM is- (X-H)^2+ (Y-K)^2= R^2 What is domain? The set of all X coordinate values OR a set of all input or dependant varibles for which the expresstion is defined as a real number. What is the range? The opposite of Domain, all the values of Y what is Set Builder Notation? an example: {X|A
