The domain for f(x) and g(x) is the set of all real numbers.
let f(x) = 2x^2 + x - 3 and g(x) = x-1
find f(x) • g(x).

Step-by-step explanation:

Use FOILing to get the answer.  Distribute x into 2x^2, to get 2x^3, then into x to get - x^2, then into -3 to get -3x.  Then distribute the -1 into the 2x^2 to get -2x^2, then into the x to get -x, then into the -3 to get 3.  Combine like terms to get the solution above.
