The domain is all real numbers, and the range is all real numbers f(x) such that f(x) ≤ 4 You can check that the vertex is indeed at (1, 4) Since a quadratic function has two mirror image halves, the line of reflection has to be in the middle of two points with the same y value Transcript Example 21 Find the domain of the function "f" (x) = (" " 2 3 5)/( 2 5 4) "f" (x) = (" " x2 3x 5)/(x2 5x 4) = (x2 3x 5)/(x2 4x 4) = (x2 3x 5)/( (x 4) 1( 4)) = (x2 3x 5)/(( 4)(x 1) ) In real numbers , the denominator cannot be zero Hence (x 4) (x 1) 0 x 4 and x 1 Hence the domain of the function will be all real numbers except 1 and 4 Hence, the domainThe domain of a function, D D, is most commonly defined as the set of values for which a function is defined For example, a function f (x) f ( x) that is defined for real values x x in R R has domain R R, and is sometimes said to be "a function over the reals" The set of values to which D D is sent by the function is

F(x)=4x+5 domain and range
F(x)=4x+5 domain and range- Explanation The denominator of f (x) cannot be zero as this would make f (x) undefined Equating the denominator to zero and solving gives the value that x cannot be solve x = 9 = 0 ⇒ x = 9 ← excluded value ⇒ domain is x ∈ R,x ≠ 9 for the range rearrange making x the subject y = 5 x −9Range The out comes or values that we get for y is known as range Domain for given function f (x) = x 3 For any real values of x, f (x) will give defined values Hence the domain is R Since we have absolute sign, we must get only positive values by applying any positive and negative values for x in the given function
