<span>a. where a freshwater river runs into an extension of the ocean</span>
Here is why:
When we solve for the inverse function (see the particular step below; when we have: " y² = x " ;
We take the "square root" of EACH SIDE of the equation; to isolate "y" as a single variable on one side of the equation;
→ √(y²) = √x ;
→ |y| = |√x| ;
y = ± √x ;
Because when we take the square root — or any "even root", for that matter—we have two solutions: of a variable, we have TWO SOLUTIONS: a positive value; and a negative values;
→ since: 1) a "negative value"; multiplied by a "negative value" ; equals a "positive value" ;
→ and as such: a "negative value" ;
multiplied by that same "negative value" ;
{that is: a "negative value", "squared (i.e "raised to the power of "2"} ; ,
→ results in a positive value ;
→ and since:
2) a "postive value"; multiplied by a positive value" ; equals a "positive value" ;
→ and as such: a "positive value" ;
multiplied by that same "positive value" ;
{that is: a "positive value", "squared (i.e "raised to the power of "2"} ; ,
→ results in a "positive value";
→ and since:
3) any given integer, in it "positive value", squared (i.e. raised to the power of "2"); results in a "positive value" ;
→and since:
4) that same aforementioned integer; in its "negative value" form, squared (i.e. raised to the power of "2"); results in that same aforementioned "positive value".

Note the following:

"Given the function: "f(x) = x² " ; Find the "inverse function" .
Let "y" = f(x) " ;
and write as: " f(x) = y = x² " ;
→ " y = x² " ;
→ Now, rewrite the equation; replacing the "y" with "x" ;
and replacing the "x" with "y" ;
→ " x = y² " ;
Now, rewrite the question; isolating "y" as a single variable;
with no coefficient (save for the "implied coefficient of "1" ) ;
→ " x = y² " ;
↔ " y² = x ;
Now, take the square root of EACH SIDE of the equation;
to isolate "y" on one side of the equation;
→ √(y²) = √x ;
→ |y| = |√x| ;
→ y = ± <span>√x .
</span>
Replace the "y" with " f ⁻¹(x)" ; to indicate that this the "inverse function" ;
and write the "inverse function" :
→ " f ⁻¹(x) = ± √x " ;

Answer:
The biosphere is that part of the earth where living things thrive and live. It is the portion of the planet that can sustain life. The earth has three other spheres:
Atmosphere
Lithosphere
Hydrospher
Ex: tundras, prairies
Oceans
