Use a table with values x = {-2, -1, 0, 1, 2} to graph the quadratic function y=-2x^2

Consider 6x2 + 6x + 1. which term immediately tells you that this expression is not a perfect square trinomial? justify your answer

For which pair of functions is (gof)(a)=|a|-2?

Factor 15x^3 - 5x^2 +6x-2 by grouping. what is the resulting expression
