Friday, March 8th, Mrs. Rosario Castillon's classes at Eagle Pass High School learned all about graphing rational functions.
A rational function is any function which can be defined by a rational fraction, i.e. an algebraic fraction such that both the numerator and the denominator are polynomials.
Students learned how to identify critical values in holes; slant, vertical and horizontal asymptotes; X & Y intercepts.
Way to go Eagles!
