With the following stated below, show that:

he points ( - 1 , - 8 ) , ( . 1 , - 2 ), and ( 2 , 1 ) lie on a common ) ine ( - 1, 6), (0, 3), ( 1 , 2 ) and ( 2, 3) lie on a common parabola. Hint: For scratch work , plug three of these points into y = a x2 + bx + obtain three equations determining a, band There is a set A such that ZU A = R There exist sets A and B such that 1A \\BIX IAI - 1BI 8 7m, n E Z such that 3 m + 5n = 11 There exist sets A and B such that A * (A UB.
