Answer:
D. The ball was thrown from an initial height of 3 feet.
Step-by-step explanation:
The generic form of the equation for (vertical) ballistic motion is ...
where g is the acceleration due to gravity, usually approximated as 32 ft/s², v₀ is the initial upward velocity, and h₀ is the initial height.
The given equation matches the situation where the object was launched vertically at the rate of 40 ft/s from a height of 3 ft.
The 3 represents an initial height of 3 feet.

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes, so we can find the slope:
Thus, the equation is of the form:
We substitute one of the points and find "b":
Finally, the equation is of the form:
