12-26.

If $f(x) = x^2$ , write an equation for each of the following transformations, then sketch a graph and write a description of the transformation.

$y = -f(x)$
Step (a):
$y = -f(x) = -x^2$

$y = f(x - 3)$
Step (b):
$y = f(x - 3) = (x - 3)^2$

$y = f(x) - 3$
Hint (c-d):
Use the same method as (a-b).

$y = f(2x)$
