Answer:
26.08 meters (rounded to 2 decimal places)
Step-by-step explanation:
This diagonal creates a right triangle with one leg 14m and another leg 22 m. We can use pythagorean theorem to figure out the diagonal (hypotenuse of the right triangle).
Pythagorean theorem tells us 
The fence needs to be 26.08 meters (rounded to 2 decimal places)
Hello.
So, you should already know that to find the inverse of a function you switch x and y and solve.
For f(x) = x² + 3, it's domain is all real numbers, and the range is y ≥ 3.
The inverse of f(x), it is

, and the equation is

= ±√(x - 3). It's domain is x ≥ 3, and the range is all real numbers.
There are many unique characteristics about inverses, like the values of x and y are switched, it's reflected on the line y = x, and the domain and range is switched.
So your final answer is
c.
f(x) domain: all real numbers, range: y ≥
3
domain: x ≥
3, domain: all real numbers.
Hopefully it makes sense! :)
I believe it is also 170 degrees as the top angle mJLK
