For the given functions f and g, complete parts (a)-(h). For parts (a)-(d), also find the domain. f(x)=2x+1;g(x)=7x−9 What is the domain of gf ? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The domain is {x∣x=79}. (Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.) B. The domain is {x∣x is any real number }. (e) Find (f+g)(2). (f+g)(2)=( Type an integer or a simplified fraction. ) (f) Find (f−g)(4). (f−g)(4)=( Type an integer or a simplified fraction. )
