2.) What is the graph of the function?

f(x)=−1x−3+2

Rational function on the coordinate plane. The curve has two branches. The left branch lies in the second quadrant. This branch passes through negative 4 comma 7 over 2 and negative 3 comma 4. The right branch begins in the third quadrant, increases into the second quadrant, and then into the first quadrant. This branch passes through 0 comma 5 over 2 and 1 comma 8 over 3.
