Which set of numbers may represent the lengths of the sides of a triangle a 1,3,4
b 4,4,9
c 5,7,9
d 8,5,3

B. 16is the absolute value

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 

Gene sure is correct 1/4 is = to 25
