There are 15 vacant units in noor's apartment building. this represents 6% of the total number of units. how many units are in noor's apartment building?

Ibelieve it's a. 2.2 - x = -10.85 (plz tell me if it's right : ) )

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
