Expert Solution
Step 1

Since we only answer up to 3 sub-parts, we’ll answer the first 3. 
Please resubmit the question and specify the other subparts (up to 3) you’d like answered.

 

Given that f(x)=x+14g(x)=x+14x+2a) (fg)(x)=f(g(x))=fx+14x+2=x+14x+2+14=5x+58x+2The denominator can not be 0. So, the domain is all real numbers except x=-2
