Will mark confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. f(x)= and g(x)=

2236.5

Step-by-step explanation:

The regression equation for predicting hiker's elevation is

y=9.06x+651.

Here x is the number of minutes.

We wish to estimate hiker's elevation after 175 minutes. For this purpose we put x=175 in the predicted regression equation.

y=9.06(175)+651

y=1585.5+651

y=2236.5

Thus, the hiker's elevation after 175 minutes is 2236.5 feet.
