Let f(x) = x+2/x+6 <br> f^-1(-6) =
GREYUIT [131]

We can explicitly find the inverse. If f^{-1}(x) is the inverse of f(x), then

f\left(f^{-1}(x)\right) = \dfrac{f^{-1}(x)+2}{f^{-1}(x)+6} = x

Solve for the inverse :

\dfrac{f^{-1}(x) + 2}{f^{-1}(x) + 6} = x

\dfrac{f^{-1}(x) + 6 - 4}{f^{-1}(x) + 6} = x

1 - \dfrac4{f^{-1}(x) + 6} = x

1 - x = \dfrac4{f^{-1}(x) + 6}

f^{-1}(x) + 6 = \dfrac4{1-x}

\implies f^{-1}(x) = \dfrac4{1-x} - 6

Then when x = -6, we have

f^{-1}(-6) = \dfrac4{1-(-6)} - 6 = \dfrac47-6 = \boxed{-\dfrac{38}7}

Alternatively, we can first solve for x such that f(x) = -6. Then taking the inverse of both sides, x = f^{-1}(-6). (The difference in this method is that we don't compute the inverse for all x.)

We have

\dfrac{x+2}{x+6} = -6

x + 2 = -6 (x + 6)

x + 2 = -6x - 36

7x = -38

\implies x = \boxed{-\dfrac{38}7}

an airplane begins to descend for a landing. the elevation g (in feet) of the airplane is modeled by the function: g(t)= 4800-30
Fynjy0 [20]

Answer:

The y-intercept in this case is 4800

Step-by-step explanation:

The equation of a line graph is ;

y = mx + c

with respect to the given equation in the question, the y-intercept in this case is 4,800

In this case the y-intercept represent the height from which the plane starts to descend
