You're sitting on the ledge of a wall that is 300 feet away from a building. You have to look up 60 degrees to see the top of the building and down 15 degrees to see the
bottom of the building. How tall is the building?

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

can you rephrase the question ? it is unclear : -)
