The product of a number b and 3 is no less than 13

3b is greater than or equal to 13

3b > 13
b > 13/3

b is greater than or equal to 13/3

6/ 11 = 0.545454 so your answer is55%

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
