1. ## Quick question

For the function:
F(x)= $(25x^2+125)/(x^2+1)$
Where f is measured in millimeters of mercury and x is measured in seconds.
What does each instantaneous rate of change (which I have found, already), illustrate?

By the way, they continuously get closer to zero.

Each instantaneous rate of change is related to the slope. It shows at what rate f(x) changes as its input, x, changes.

If you are familiar with elementary calculus, you would know this as the derivative. Basically it allows us to move along a function by describing the slope at any particular point of said function.

What are the units of:

$\frac{d}{dt}F(t)$
