CPM Homework Help : PC Problem 2-103

Continuous Piecewise graph: Left piece, upward parabola, vertex at the point (0, comma negative 4), ending at the point (3, comma 5). Right piece, ray starting at the point (3, comma 5), passing through the point (6, comma 2). Given the graph of $f(x)$ , sketch each of the following transformations.

$-f(x)$
Hint (a):
The negative gives all of the $f(x)$ -values the opposite sign.
What does this do to the graph?
$f(x+2)-1$
Hint (b):
The $2$ and $-1$ shift the graph. Which directions?
$\frac{1}{2}f\left(x\right)$
Hint (c):
All of the original function values are halved.
