Acommercial jet airplane climbs at takeoff with slope m=4/9. how far in the horizontal direction will the airplane fly to reach am altitude of 20,000 ft above the takeoff point?

solve for "h".

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
