Given the equation:

where: (h) is the height above the planet's surface in kilometers.
T(h) is the temperature in Celsius.
If we have calculated the function:

(a)
so, the output is the last function will be the height above the planet's surface.
So, the statements that best describe the last function is:
(b) the expression for the last function will be as follows:

so, the answer for part (b) is:

Part (c): we need to find:

So, By substitution with x = 33 into the equation of part (a) as follows:

so, the answer of part (c) = 6.2
