2.2.2: Identifying the Domain of a Quadratic Function
WORDS TO KNOW
DOMAIN: The domain of a function is all input values (x-values) that satisfy the function without restriction.
RANGE: The range of a function is all the output values (y-values) that satisfy the function without restriction.
AVERAGE RATE OF CHANGE: The average rate of change of a function is the rate of change between any two points of a function. It is a measure of how a quantity changes over some interval, which is a SLOPE.
