- The function f is defined by
$$\mathrm { f } ( x ) = \frac { x + 3 } { x - 4 } \quad x \in \mathbb { R } , x \neq 4$$
- Find ff(6)
- Find \(f ^ { - 1 }\)
The function \(g\) is defined by
$$g ( x ) = x ^ { 2 } + 5 \quad x \in \mathbb { R } , x > 0$$
- Find the exact value of \(a\) for which
$$\operatorname { gf } ( a ) = 7$$
