Answer:
1) Option B is correct.
The inverse of the function, T⁻¹(x), represents the The height above the surface (in kilometers) when the temperature is x degrees Celsius.
2) T⁻¹(x) = 12.2 - 0.4x
3) T⁻¹(15) = 6.2 m
Step-by-step explanation:
1) The inverse of a function is a function that reverses the effects of the original function on the variable that determines the original function's value.
T(h) = 30.5 - 2.5h
The original function takes the height in kilometres and converts it to temperature at that point in degree Celsius, So, the inverse function will take the temperature in degree Celsius and produce the corresponding height in kilometres.
So, it is the The height above the surface (in kilometers) when the temperature is x degrees Celsius.
The inverse functuon is given as T⁻¹ (x)
2) To obtain T⁻¹(x)
T(h) = 30.5 - 2.5h
We make h the subject of formula
2.5h = 30.5 - T
h = (30.5 - T)/2.5
h = 12.2 - 0.4T
T⁻¹(x) = 12.2 - 0.4x
3) T⁻¹(x) = 12.2 - 0.4x
when x = 15°C
T⁻¹(15) = 12.2 - 0.4(15) = 6.2 m

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
to be a linear function the change in X and the change in Y has to be the same hence slope
A. x changes by+ 1 see 2,3,4,5, and y changes by +5, +7, +9 so A is not a linear function
B. X changes by -1 in all, y changes +1 for first 3 then -1 last, so B is not a linear function
C. X changes by +1 for all and y changes by -6 for all so is it is a linear function
D x changes by +1 for all and y changes by -1, +1, +3 so no linear fn.
C. 3/2
I took the quiz and it was right!!!
