An object was dropped off the top of a building. The function f(x)=-16x^2+400represents the height of the object above the ground, in feet, x seconds after being dropped. Find and interpret the given function values and determine an appropriate domain for the function.

Domain exists on all real values and it is expressed according to the notation:

(-∞, ∞)

Step-by-step explanation:

The domain of a function is the values of the input variables x that will make the function exist.

Given the function f(x)=-16x^2+400

Since the variable x is a perfect square, this means that the function f(x) will exists for all values of x. The domain is expressed as:

(-∞, ∞)

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
