SOLUTION: Find the difference quotient and simplify the answer: f(s)=9s^2 minus 7s; f(5+h)-f(5)divided by h. h cannot be zero

Question 771766: Find the difference quotient and simplify the answer:
f(s)=9s^2 minus 7s; f(5+h)-f(5)divided by h. h cannot be zero
Answer by oscargut(2103) (Show Source): You can put this solution on YOUR website!
(s)=9s^2 minus 7s; f(5+h)-f(5)divided by h. h cannot be zero
f(5+h)=9(5+h)^2 -7(5+h) = 9(h^2+10h+25)-7h-35 =9h^2+83h+190
f(5) = 9(5^2)-7(5) = 190
Then
(f(5+h)-f(5))/h = (9h^2+83h)/h = 9h+83
Answer: 9h+83
