Solving for a Variable
Scientists have found a relationship between the temperature and the height above a distant planet's surface. $T(h)$, given below, is the temperature in Celsius at a height of $h$ kilometers above the planet's surface. The relationship is as follows.
\[
T(h)=48.5-2.5 h
\]
Complete the following statements.
Let $T^{-1}$ be the inverse function of $T$. Take $x$ to be an output of the function $T$.
That is, $x=T(h)$ and $h=T^{-1}(x)$.
(a) Which statement best describes $T^{-1}(x)$ ?
The ratio of the temperature (in degrees Celsius) to the number of kilometers, $x$.
The height above the surface (in kilometers) when the temperature is $x$ degrees Celsius.
The reciprocal of the temperature (in degrees Celsius) at a height of $x$ kilometers.
The temperature (in degrees Celsius) at a height of $x$ kilometers.
(b) $T^{-1}(x)=$
(c) $T^{-1}(33)=$
