(1) Sketch the graph of $f _ { 0 }$ in the interval [-2;2] in the figure. (2) The graph of $f _ { 0 }$ encloses an area with the $x$-axis in the second quadrant.
Determine the area $A _ { 0 }$ of this region by calculation. [For verification: $A _ { 0 } = 2,25 \mathrm { FE }$.] (3) Given is the line $g : y = - 2 x , x \in \mathbb { R }$.
Determine the ratio in which the line $g$ divides the area from (2).
