Step 2

The domain of a function h(x) is the set of all the values of x for which the function is defined and the value of the function h(x) exists.

The rational function h(x) = n(x)/d(x) is not defined at the points where d(x) = 0.

Step 3

Simplify the function f(x) ...

f(x)
x14r45
x5x9x 45
x5
x(x+5)+9(x+5)
x+5
|(x+5)(x+9)
