For a given takeoff weight, the takeoff distance increases if the air temperature increases. For a specific example, if a KC135 weighs 200,000 lbs, the takeoff distance is modeled by f(t)=1/3(t+145)^2  67. If D = f(t) , where D is the takeoff distance as a function of t, temperature which is measured in °C and is valid for the temperature domain: [0° to 30°].
Does the inverse exist. If so, interpret the meaning of the inverse function in terms of the relationship between distance and temperature. Within your explanation, include a specific example using correct function notation.
Dont really know where to start on this one. Any help would be greatly appreciated.

solve for t is the first step.
What does the equation mean?
