Here is the first sign that should tell you this isn't a rectangle.

d=_/w^2+l^2 is the equation to solve the diagonal of a rectangle

if you plug in 21 and 20, d would equal 29 not 28 so for that reason alone it is not a rectangle.

I am about 90% sure the correct answer is B. I hope this helps let me know if I was right.

Option B!

For the function f(x) = x2 -12, find (f o f-1)(4) A. 0 B. 4 C. 10 D. 6

We actually don't need to do any computation. By definition, the inverse function $f^{-1}$ changes the role of input and output. So, if a function f maps x onto y, the inverse function maps y onto x.
