Given f(x) =3x-1/2 solve for f^-1(4)
bazaltina [42]

f(x) = 3x - 1/2

f^{-1}(x) is the inverse of f(x). Let y = f(x)

y = 3x - 1/2

To find the inverse function, replace y with x and x with y

x = 3y - 1/2

After solving and simplifying the equation for y, you will get the following equation

y = x/3 + 1/6

This is the inverse of f(x). Now, substitute x = 4

y = 4/3 + 1/6

= 8/6 + 1/6

= 9/6

= 3/2

That should be your answer. Let me know if you need any clarifications, thanks!

Given this proportion, what ratio completes the equivilent proportion a/8?
Paladinen [302]
To solve this problem you must follow the steps below:

 You have a/b=8/15, Then:

 1. You must divide in both side of the given proportion by 8:

 a/bx8=8/15x8

 2. When you simplify, you obtain:

 a/8b=1/15

 3. Now, you must multiply both sides by "b", as below:

 axb/8b=1xb/15

 4. Finally, when you simplify, you have:

 a/8=b/15
