Answer:
x - y ≥ -1
Step-by-step explanation:
y ≥ x + 1
x - y ≥ -1
Answer:
f(x) and its inverse are the same
Step-by-step explanation:
<u>The inverse function
</u>
If y=f(x), the inverse function
is defined such as

To find the inverse function, there is a practical method:
a) Change letters x for y and vice-versa
b) Isolate y in terms of x only
c) 
In our case, 
a) Interchanging letters

b) Isolate 
c) 
As we can easily see, f and its inverse are exactly the same

Yes true it's basically saying any positive number squared is bigger than the number being squared now give me brainliest
