EVALUATING FUNCTIONS The symbol f(x) represents the real number in the range of the function f corresponding to the domain value x. Symbolically, f:x→f(x). The ordered pair (x, S(x)) belongs to the function f. Ifxisa real number that is not in the domain of f, then fis not defined at x and f(x) does not exist. Examples: 15 a) Find f(6), S(a), and f(6+a) for f(x) 三 3° X - b) Find g(7), g(h), and g(7+h) for g(x) = 16+ 3x x. 2 Find k(9), 4k(a), and k(4a) for k(x) Vx c) 2 For the above functions, determine the resulting domain. Solutions: a) b) c)

EVALUATING FUNCTIONS The symbol f(x) represents the real number in the range of the function fcorresponding to the domain value x. Symbolically, f:x → S(x). The ordered pair (x, f(x)) belongs to the function f. If xis areal number that is not in the domain of f, then fis not defined at x and f(x) does not exist. Examples: 15 a) Find f(6), f(a), and f(6+a) for f(x) x -3 b) Find g(7), g(h), and g(7+h) for g(x) = 16+ 3x - x。 2 c) Find k(9), 4k(a), and k(4a) for k(x) = 2 For the above functions, determine the resulting domain.

(I)が関数で(ii)が関数じゃないらしいのですが何故か教え欲しいです

Determine whether each set specifies a function. If it does, then state the domain and range. 2) i) S = {(I1,4), (2,3), (3,2), (4,3), (5,4)} T= {(1,4), (2,3), (3,2), (2,4), (1,5)} Solutions: i) Prepared by DZ Page 3
