The function below describes the relationship between the height h and the width w of a rectangle with area 70 sq. units. h(w)= 70/w what is the domain of the function?

Step-by-step explanation:

The area of a rectangle is given by:

In this case, we have the height replacing the length.

The area of the rectangle is 70.

Dividing through by w gives:

Or to show that H is dependent on w, we write

Domain is the set of all real numbers for which the function is defined.

Therefore the domain is all real numbers except 0.
