Did you know that a rational function can also represent inverse variation?

For example, a rational function is a polynomial divided by another polynomial.

y = 20/x is a polynomial function, but it's also inverse variaton.

y = k/x reprsents inverse variation, y varies inversely as x and k is the constant.

In the above example, the constant is 20.

A rational function is any function which can be written as the ratio of two polynomial functions. Neither the coefficients of the polynomials nor the values taken by the function are necessarily rational numbers.trigonometric functions

ReplyDeleteThanks for the comment, yes you are correct with your statement. Another such example would be (2x^2 + 3x + 4)/(4x - 3), etc. Both the numerator and denominator are polynomial functions.
