#### Answer

$$f(x)=|x-2|+3,\quad g(x)=-|x+2|-1.$$

#### Work Step by Step

1) The purple function. We see that it has a cusp when $x=2$ and $y=3$. This means that the function $y=|x|$ has to be shifted upwards by $3$ and rightwards by $2$. There is no rescaling since the function in the linear pieces increases or decreases by $1$ unit when $x$ changes by $1$ so the equation is
$$y=|x-2|+3.$$
2) The blue function. This function has a cusp when $x=-2$ and $y=-1$ and it point upwards which means that it is inverted with respect to $y=|x|$. There are several ways to obtain this function, one of them is: invert it with respect to $x$ axis and then shift it leftwards by $2$ and downwards by $1$:
a) Inversion $|x|\to-|x|$;
b) Leftwards shift $-|x|\to-|x+2|$
c) Downwards shift $-|x+2|\to-|x+2|-1$
The function is then
$$y=-|x+2|-1.$$
