The domain of a function is where we have a value for x.
Since that's the case the domain of f(x) = {x e R / 1 ≤ x < 5}
We see that we have a value for x = 1 cuz we have a filled circle, but we don't have a value for x = 5, look at the unfilled circle 
So, our x can vary between 1 and 5, but can't be 5.
 
        
             
        
        
        
Answer:
15 feet
Step-by-step explanation:
Since this is a square the sides are of the same length. 
Now the side multiplied by itself gives 225. Hence the length of the side is a number which multiplied by itself gives 225. It is easy to see that 15 × 15 = 225. Therefore the side is 15 feet long.
