Summary & Key Takeaways

The task is to find the rate of change of the vertical distance between two functions (h) with respect to x when x=1.8.

By subtracting one function (g) from another function (f), h(x) is defined.

The derivative of h(x) can be calculated using a calculator, and when x=1.8, the rate of change is approximately 3.812.
