Extreme Value Theorem. If f ( x ) is continuous on the closed interval [ a , b ] then there exist numbers c and d so that, 1. a £ c , d £ b , 2. f ( c ) is the abs. max. in [ a , b ] , 3. f ( d ) is the abs. min. in [ a , b ] .
The natural domain of f(x) = √ x2 − 5x + 6 consists of all numbers x for which x2 − 5x + 6 > 0 (in order for the square root to assume a real value). Since x2 − 5x + 6 = (x − 3) (we use the formula for roots of a quadratic equation, x =. 2)(x −. 5±√52−4·6·1. 2 ), we would like to find x for which (x − 2)(x − 3) > 0.
If only the rule y = f(x) is given, then the domain is taken to be the set of all real x for which the function is defined. For example, y = √ x has domain; all real x ≥ 0. This is sometimes referred to as the natural domain of the function. 1.1.4 Range of a function For a function f: X → Y the range of f is the set of y-values such that ...
