1.Compose and simplify an equation of a family of quartic polynomial functions with irrational roots i 8 and rational roots i 1. 8) Write an equation for a member of this family with y-intercept ( 4) b)Sketch the graph of this function. Fully explain how you do this without using technology] c)State the intervals where this function is negative (use bracket notation). Fully explain how you do this without using technology. d)From the graph, is this function odd/eveneither? Explain. Justify your conclusion algebraically
