PRESENTATION OUTLINE
DOMAIN
domain of a function is the set of all possible input values (often the "x" variable)
RANGE
The difference between the lowest and highest values.
FUNCTION
a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
VERTICAL LINE TEST
a visual way to determine if a curve is a graph of a function or not.
SLOPE
he slope or gradient of a line is a number that describes both the direction and the steepness of the line.
SLOPE INTERCEPT FORM
the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
POINT-SLOPE FORM
the equation of a straight line in the form y − y1 = m(x − x1) where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line
X-INTERCEPT
The x-intercept of a line is the point at which the line. crosses the x axis.
Y-INTERCEPT
where the line crosses the y-axis
DEPENDANT VARIABLE
A variable that depends on one or more other variables.
INDEPENDENT VARIABLE
A variable that does not depend on one or more other variable.
