How do you find the inverse of FX 1 2x 3?

How do you find the inverse of FX 1 2x 3?

Add x x and 0 0 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=2x+6 f – 1 ( x ) = 2 x + 6 is the inverse of f(x)=12x−3 f ( x ) = 1 2 x – 3 .

What is the inverse of f/x )= 1 2x 3 2?

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=2x−3 f – 1 ( x ) = 2 x – 3 is the inverse of f(x)=12x+32 f ( x ) = 1 2 x + 3 2 .

How do you find the inverse of 2x 3?

1 Answer

  1. To make the function easier to work with, first replace f(x) with y : y=2x−3.
  2. To find the inverse of the relation, swap x and y : x=2y−3.
  3. Solve for y : x+3=2y.

How do you graph x3 – x – 1?

You can rewrite the equation as x3 −x −1 = 0 as the first step. Then graph the following: f (x) = x3 − x − 1. Click on where the graph intersects the x-axis. This point should be (1.325, 0). Therefore, the answer is x = 1.325.

What is x – 1 = -3-1 = -4?

If x = -3 then x – 1 = -3-1 = -4 So the function f evaluated at -4 now means the new value is to be = -4. You do not put -3 into the right hand side of the equation first. you would have y = 2* (-3) + 3 = -6 + 3 = -3.
