May 20, 2023 · Step 1: The radical in the denominator is \sqrt {3} 3. Step 2: The rationalizing factor is \sqrt {3} 3. We select this because multiplying \sqrt {3} 3 by itself gives us 3, a rational number, thereby removing the radical from the denominator. Step 3: Multiply the numerator and denominator by the rationalizing factor: 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 ).The following identities may be used to rationalize denominators of rational expressions.
