Find the quotient. simplify your answer s-4/s / 8/s
lapo4ka [179]

Your input: find the difference quotient for f(s)=s−12s2.

A difference quotient is given by f(s+h)−f(s)h

To find f(s+h), plug s+h instead of s:

f(s+h)=s−12s2

Finally, f(s+h)−f(s)h=(s−12s2)−(s−12s2)h=0

Answer: the difference quotient for f(s)=s−12s2 is 0.
