Question 5 (1 point) Godzilla is standing on top of a 128 foot tall building and throws a person off of th building. The initial speed that the person is thrown is 32 ft/sec. The height of the person as a function of time can be modeled by the function h(t) = -16t2 + 32t + 128. How long will it take for the person to hit the ground? 4 seconds 4 1.5 seconds 0.75 seconds 2 seconds Question 6 (1 point)​

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

the answer is d
