If f(x) = 5x, what is f–1(x)?

yulyashka [42]

Keep in mind that an inverse function is simply the reversal of the x and y coordinates of the parent function. For every (x,y) of the parent function, the inverse function has a point (y,x). With the conceptual part out of the way, finding the inverse function is relatively straight forward. If:

y=5x then the inverse function will be what you have when you solve for x and then reverse the variable labels...ie.

y=5x so

x=y/5 now reverse the variable labels...

y=x/5 this is the inverse function of y=5x or as your problem notation stated:

f^-1(x)=x/5

Write an equation that expresses the following relationship.

AlexFokin [52]

The equation become u = k p^2 / d.

According to the statement

we have given that some conditions for the equations and we have t make the equation from the given equations.

So, For this purpose, we have given that

The equation in which u is varies directly with the square of p and inversely with d and use the k as the constant of proportionality.

So, From all these above the equation will become is

u = k p^2 / d

In latex form the equation write as :

$u = \frac{kp^{2}}{d}$

In this equation all the given conditions are applicable.

So, The equation become u = k p^2 / d
