On this would be greatly appreciated

The graph of fx shown below has the same shape as the graph of gx = 3x^2 but is shifted down 2 units

The graph below could be the graph of which exponential function?

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
