1. Polynomial Functions [refer to Part A: Polynomial Functions page} The forces acting on a horizontal support beam in a house cause it to sag by d centimeters, 3: meters from one end of the beam. The relationship between d and x can be represented by the polynomial function equation . {x}: ' ll-[momma \"3] 185 Graph the function, using technology, and determine the domain over which the function models the relationship between d and x. 1What is the least amount of sag in the support beam and where does it occur? a show a solution using both graphical and algebraic models.
