(I have Finals and I really need help) A = 2, 4, 6, 8, 10 and B = 1, 2, 3, 4, 5

Find the union: A The union of B.

{7, 9}

{1, 3, 5}

{1, 2, 3, 4, 5, 6, 8, 10}

{2, 4}

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
