Expert Solution
Step 1

we have to find the domain of the composite function fog.

the given functions are:

f(x)=5x+9

g(x)=x+6

Step 2

the value of fog is:

f(g(x))=f(x+6)=5x+6+9=5x+15

therefore the composite function fog is:f(g(x))=5x+15

as we know that the domain of the function is the set of values of the independent variable for which the function is defined.

so we can notice that the composite function fog is defined when the denominator of fog is not equal to zero.
