We have that
y = 2x²<span> + 2

step 1

</span><span>exchange the value of x for y and the value of y for x
</span>y = 2x² + 2------> x=2y²+2

step 2
clear y variable
 x=2y²+2----> 2y²=x-2----> y²=[(x-2)/2]-----> y=(+/-)√[(x-2)/2]

step 3
the inverse is
f(x)-1=(+/-)√[(x-2)/2]

Readme [11.4K]

The flux across a surface is an indicator of the rate at which fluid is flowing through it when there is a fluid flowing in three dimensions and a surface positioned inside that space.

<h3>What is Electric Flux?</h3>
  • A feature of an electric field is electric flux. One way to conceptualize it is as the quantity of forces interacting in a specific space.
  • According to conventional wisdom, electric field lines begin with positive electric charges and conclude with negative charges.
  • A closed surface's field lines are seen as negative when they are directed into it, and as positive when they are directed out of it.
  • Every field line that is directed into a closed surface continues through the interior and is often directed outward somewhere else on the surface if there is no net charge present within the surface.
  • The net, or total, electric flux is zero because the size of the negative and positive fluxes are just about equal.
  • A closed surface that contains a net charge will have a total flux that is proportional to the enclosed charge, positive if it is positive and negative if it is negative.
