Rational expressions usually are not defined for all real numbers. The real numbers that give a value of 0 in the denominator are not part of the domain. These values are called restrictions. Simplifying rational expressions is similar to simplifying fractions. First, factor the numerator and denominator and then cancel the common factors. To find the x-intercepts, I first set the function equal to zero. A generic rational function can be written as $ f(x) = \frac{p(x)}{q(x)} $, with ( p(x) ) being the numerator and ( q(x) ) being the denominator.The x-intercepts occur when the numerator is zero because a fraction is zero only when its numerator is zero. So, I solve the equation ( p(x) = 0 ). In order to rationalize the denominator, you must multiply the numerator and denominator of a fraction by some radical that will make the 'radical' in the denominator go away. Below is some background knowledge that you must remember in order to be able to understand the steps we are going to use. Writing Radicals as Rational Exponents. Write 4 a 2 7 4 a 2 7 using a rational exponent. The power is 2 and the root is 7, so the rational exponent will be 2 7. 2 7. We get 4 a 2 7. 4 a 2 7. Using properties of exponents, we get 4 a 2 7 = 4 a −2 7. 4 a 2 7 = 4 a −2 7. If the denominator of a fraction includes a rational number, add or subtract a surd, swap the + or – sign and multiply the numerator and denominator by this expression. Rational Expression. A rational expression is an expression of the form p ( x) q ( x), where p and q are polynomials and q ≠ 0. Remember, division by 0 is undefined. Here are some examples of rational expressions: − 13 42 7y 8z 5x + 2 x2 − 7 4x2 + 3x − 1 2x − 8. Notice that the first rational expression listed above, − 13 42, is ... Sketch the oblique asymptote of h ( x ). Because the numerator of this rational function has the greater degree, the function has an oblique asymptote.
