The linear functions given are f(x)=5x+2 and g(x)=x-1. Find the sum function (f+g)(x), the difference function, (f-g)(x), the product function, (fg)(x), and the quotient function, (f/g)(x). The domains of f(x) and g(x) are found and their intersection is used to find the domain of f+g, f-g, and fg. The domain of f/g is found by taking this intersection and excluding all values of x that make the denominator (g(x)) equal to zero. All the domains are written in interval notation.
