 Adding rational functions 2008-04-29 Jonathon pose la question :1/(x+3) + 1/(x^2+5x+6) =Penny Nom lui répond. Irrational functions 2007-10-01 alicia pose la question :i have a question about irrationals functions. i have been using them quite some time now, but i wonder where they can be found in daily life? i hope you can help me,Harley Weston lui répond. Rational functions 2005-04-05 Nicole pose la question :My name is Nicole and I am a teacher at Weyburn Comprehensive School. I am currently teaching both Math B30 and Calculus 30 at the school and I have a question about rational functions. I know that if a rational function (by definition) has common factors in the numerator and the denominator then it is not a rational function (math b30) however in calculus this common factor creates a hole in our graph. Can you explain to me why a common factor or constant does not give us a rational function?Penny Nom and Leeanne Boehm lui répond. Polynomials 2004-01-25 Bruce pose la question :A polynomial is defined as Polynomial functions are functions that have this form: f(x) = anxn + an-1xn-1 + ... + a1x + a0 The value of n must be an nonnegative integer. That is, it must be whole number; it is equal to zero or a positive integer. The coefficients, as they are called, are an, an-1, ..., a1, a0. These are real numbers. Questions: why must n be positive? what are some historical facts about the evolution of the definition? Harley Weston lui répond.
