Mathematics: Megan and Desmond each added the same amount of water to their aquariums. Megan mixed 5 mL of a chemical solution with every gallon of water for her aquarium. Desmond mixed 8 mL of the chemical solution with every 2 gallons of water for his aquarium. Which of these statements is true? A Megan used more solution per gallon of water than Desmond, because 5 mL is greater than 2 mL. B Megan used more solution per gallon of water than Desmond, because 5 : 1 is greater than 8 : 2. C Desmond used more

Step-by-step explanation:

Hello,

there is not always an intersection point

let's take the example of on the appropriate domain

$f(x)=e^x \ \ \ f^{-1}(x)=ln(x)$

there is no intersection point

if there is one it means that the point (x,f(x)) and the point (x, $f^{-1}(x)$ ) is the same so that have to solve

$f(x)=f^{-1}(x)$

for instance if we take

$f(x)=x^2 \ \ \ f^{-1}(x)=\sqrt{x} \ \ \ for \ x = 0$

intersection point are for x >= 0

$x^2=\sqrt{x} x^4=xx^3=1 \ or \ x=0 x = 1 \ or \ x=0$

hope this helps
