How do you know if a number is rational
WebA rational function is a function that is the ratio of polynomials. Any function of one variable, x, is called a rational function if, it can be represented as f(x) = p(x)/q(x), where p(x) and q(x) are polynomials such that q(x) ≠ 0.For example, f(x) = (x 2 + x - 2) / (2x 2 - 2x - 3) is a rational function and here, 2x 2 - 2x - 3 ≠ 0.. We know that every constant is a polynomial and … WebNov 16, 2011 · From wikipedia: The square root of x is rational if and only if x is a rational number that can be represented as a ratio of two perfect squares.
