Tre'Quan reads at a constant rate that lets him complete 4 chapters each week. He starts reading a book with 42 chapters. Which equation below models the number of chapters that he has left to read , y, after x days?

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 

Wish i could u but i just don’t know the answer
