you get a polynomial, in fact you get a line the domain of any polynomial is all real numbers

the second one just means divide \[\frac{5x+4}{2x+5}\]
 one year ago

satellite73Best ResponseYou've already chosen the best response.1
to find the domain, set \(2x+5=0\) and solve for \(x\) then say "all real numbers except your answer"
