A rocket is launched from the top of a 30 foot cliff with an initial velocity of 150 feet per second. The height, h, of the rocket after t seconds is given by the equation
h = - 1672 +150t + 30. How long after the rocket is launched will it be 20 feet from the ground?

The only number less than 8 that can equal 12 would be 6, 36 is the dividend

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
