Jennifer's basketball team played 18 games this season, and they won twice as many games as they lost. how many games did they lose?

She lost 6 games. Since she won twice the amount she lost (6) you would multiply 6 by 2 to get the number of games she won, which would be 12. To check if you are correct you could add the games lost (6) to the games won(12) which should give you the total games played (18)

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
