Answer:

  • f(6) = 5
  • f(a) = 15/(a -3)

Explanation:

You want to find f(6) and f(a) when f(x) = 15/(x -3).

Substitution

To evaluate a function, put the argument where the variable is and simplify as needed.

F(6)

Put 6 where x is:

f(6) = 15/(6 -3) = 15/3

f(6) = 5

F(a)

Put 'a' where x is:

f(a) = 15/(a -3) . . . . . . cannot be simplified
