Identify the transformation of the function f (x ) = 2x − 1 + 4.

Question

Identify the transformation of the function f (x ) = 2^{x − 1} + 4.

  

right 1; up 4

left 4; up 1

right 4; down 1



left 1; up 4

 

Answer 1

To move right by n units, replace the x with x-n

To move left by n units, replace the x with x+n

To move up n units, add n to the whole equation

To move down n units, subtract n from the whole equation

Now let's apply the rules:

1. right 1; up 4 2^(x-1)-1 + 4 + 4 = 2^x-2 + 8
2. left 4; up 1 2^(x+4)-1 + 4 + 1 = 2^x+3 + 5
3. right 4; down 1 2^(x-4)-1 + 4 - 1 = 2^x-5 + 3
4. left 1; up 4 You try this one
