Hello.

1. Switch y and x.
x = 10y^2 - 4
2. Isolate y.
x + 4 = 10y^2
(x + 4)/(10) = y^2
y = sqrt[(x + 4)/(10)]
3. Replace y with f^-1(x)
f^-1(x) = sqrt[(x + 4)/(10)]

Good luck to you!

We are given with the rectangle shaped deck which has  a width of 29 feet and a perimeter of 134 feet. the perimeter of a rectangle is equal to twice the sum of length and width. hence the equation goes : 

134 ≤ 2* (29 + L)
67 <span>≤ 29 + L 
38 </span><span>≤ L 

length should be greater or less than 38 feet</span>
