Question

For all s<0, what happens to the value of (s^3-s^2)/(s^2)+s, as "s" decreases?

A It decreases in proportion to s^3.

B. It decreases in proportion to s.

C. It remains constant.

D. It increases in proportion to s^3.

E. It increases in proportion to s.

Answer 1

\[\frac{ s^3 +s^2 }{ s^2 + s }= \frac{ s^2 (s+1)}{s(s+1)}=s\] by factorising the top and bottom and then cancelling.
So it will decrease in proportion to s.

Answer 2

(It is in fact equal to s)
