Pressure Average barometric pressure varies with the altitude of a location. The greater the altitude is, the lower the pressure. The altítude A is measured in feet above sea level. The barometric pressure P is measured in inches of mercury (in. Hg). The altitude can be modeled by the function A(P)=90,000-26,500 ln P .
What is a reasonable domain of the function? What is the range of the function?
