Heather is considering purchasing an item that costs $9. The sales tax in Heather's area is set at 6.8%. What is the total purchase price that Heather would be charged on this purchase? Round your answer to the nearest cent, if necessary.

It would be 3x+3 because the skate rental is for the day and she spent 3 hours skating. hope this !

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
