Evaluate h (0). what does this value tell you? Explain in the context of the problem

An equation is needed to evaluate h (0).

When you evaluate h (0), you find the y-intercept of the graph because the independent variable inside the brackets, probably x or t, equates to 0.

The problem is needed for its context to be explained.

Although in most math problems, when h (x) form is used, h usually represents height.

I assume h (0) is the initial height, maybe the height that the rocket was launched or the height that the person who threw the ball is.
