Answer:

g(f(x))=x g ( f ( x ) ) = x , f−1(x)=√x+5,−√x+5 f - 1 ( x ) = x + 5 , - x + 5 is the inverse of f(x)=x2−5 f ( x ) = x 2 - 5 .

Step-by-step explanation:

( f ( x ) ) = x , f−1(x)=√x+5,−√x+5 f - 1 ( x ) = x + 5 , - x + 5 is the inverse of f(x)=x2−5 f ( x ) = x 2 - 5 .

<h3>What is an Equation ?</h3>

An equation is a mathematical statement formed when two algebraic expressions are equated by an equal sign.

It is given in the question that

When four gallons are added to a tank that is one-third full

the tank is then one-half full.

Let the capacity of the tank is x gallons

The equation can be formed for the capacity of the tank as

(1/3)x +4 = (1/2)x

(1/3)x -(1/2)x = -4

(1/6)x = 4

x = 24 gallons.

Therefore the capacity of the tank in gallons is 24 gallons.
