11-22.
  1. Given the quadratic function f(x) = (x − 3)2, find the new expression for each part below and describe the transformation. Homework Help ✎

    1. f(x) − 1

    2. 1 · f(x)

    3. f(x − 1)

    4. f(1x)

See problem 11-10 for additional help.

Substitute (x − 3)2 for f(x).
f(x) − 1
(x − 3)2 − 1

(x − 3)2 − 1 or x2 − 6x + 8
Shifted down 1.

See the help for part (a).

Reflected over x-axis.

(x − 4)2 or x2 − 8x + 16

Substitute −1x for x in the original function.
