Tshirts cost 12.99 each for the first 5 shirts purchased. each additional t-shirt costs $4.99 each. describe and correct the error in the graph at the right that represents the relationship between total cost and number of shirts purchased

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
