D: -25/27
-5/6 ÷ 9/10 = 5/6 x 10/9 *when diving fractions, use recipricals.*
-5/6 ÷ 10/9 = - 25/27 *just multiply each numerator and denominator*

Answer: 14
<u>Step-by-step explanation:</u>
f(x) = 3x + 2
To find f⁻¹, swap the x's and y's and solve for y --> Note: f(x) is y
x = 3y + 2
x - 2 = 3y
f(f⁻¹(14)) = f(4)
f(4) = 3(4) + 2
= 12 + 2
= 14
NOTE: the simplified version is .... f and f⁻¹ cancel out, leaving you with 14
Therefore the answer is B.
Hope this helps !
