find A for Bは「BにAを代入しなさい」という意味だと思います。
たとえばa)は
15/(x-3)のxに6とaと6+aをそれぞれ代入すればいいのかなと。

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.
Solutions:
a)
b)
c)
