Find explicit formulas (in terms of $x$) for the following functions, and describe in words how the graphs of the following functions differ from $f(x) = \sqrt{x}$. For example, the explicit form of $g(x)=f(x+2)$ would be $g(x)=\sqrt{x+2}$.

a) $p(x) = f(x - 2)=$
The graph of $p(x)$ is the same as the graph of $f(x)$ shifted ? right left up down by .

b) $q(x) = f(x - 4)=$
The graph of $q(x)$ is the same as the graph of $f(x)$ shifted ? right left up down by .

c) $r(x) = f(x - \log(8))=$
The graph of $r(x)$ is the same as the graph of $f(x)$ shifted ? right left up down by .

Hint:
