MOSE9-12.A.APR.7 Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtracti
multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.
MG819-12. F.IF.4 Using tables, graphs, and verbal descriptions, interpret the key characteristics of a function which models the relationship
between two quantities, Sketch a graph showing key features including; intercepts, interval where the function is increasing, decreasing, posi
negative; relative maximums and minimums; symmetries; end behavior; and periodicity, (Limit to radical and rational functions,)
