Answer :

Answer:

  • vertical expansion by a factor of 2
  • translation right 3 units
  • translation up 4 units

Step-by-step explanation:

You want the transformations involved in the absolute value function 2|x-3|+4.

Transformations

The transformations we're usually concerned with include ...

  • vertical scaling
  • horizontal scaling
  • translation right
  • translation up

The scale factors can be positive or negative (indicating reflection), greater than 1 (expansion) or less than 1 (compression). The translations can be positive or negative (in the opposite direction).

Application

The original absolute value function |x| has been transformed to ...

  a|x -h| +k

where 'a' is the vertical scale factor, and (h, k) represent the translation (right, up).

Comparing to 2|x -3| +4, we see a=2, h=3, k=4.

The function has been vertically expanded by a factor of 2 and translated right 3 units and up 4 units.
