Well, if the elevation is 45 degrees, the height of the tree and the distance to the truck are the same.

The elevation is more than that, so the distance to the truck is less than the height of the tree.

The only answer that reflects that is D.

Answer:

b) $f^{-1}(x) = \frac{4x+5}{3}$

Step-by-step explanation:

b) To find the inverse function, switch the $x$ and $y$ variables and solve for $y$ :

$f(x) = \frac{3x-5}{4}\\y = \frac{3x-5}{4}\\x = \frac{3y-5}{4}\\4x = 3y-5\\4x+5 = 3y\\\frac{4x+5}{3} = y\\f^{-1}(x) = \frac{4x+5}{3}$

Verify Answer:

$f(1) = \frac{3(1)-5}{4} = -0.5\\f^{-1}(-0.5) = \frac{4(-0.5)+5}{3} = 1$
