If f(x)={{3,5),(2,4),(1,7)}, g(x)=√(x-3), h(x)={3,2),(4,3),(1,6)}, and k(x)=x^2+5

1. (f+h)(1)=

2. (k-g)(5)=

3. (f·h)(3)=

4. (g·k)(7)=

Directions: Construct each of the functions, then find the domain.

5. f^(-1)(x)=

hint: this means the inverse of f.

6. k^(-1)(X)=

7. 1/(f(x))=

8. (kg)(x)=

hint: (kg)(x)=k(x)g(x)
