SOLUTION: Let f(t) = 4/(t^2). Use the defintion of the derivative to determine f'(-1) Let g(x) = 1/(x+1). Use the defintion of the derivative to determine g'(1) Please show how this

Question 1008996: Let f(t) = 4/(t^2). Use the defintion of the derivative to determine f'(-1)
Let g(x) = 1/(x+1). Use the defintion of the derivative to determine g'(1)

Please show how this is done
Thank you

4(T+2)^-1
DERIVATIVE IS 4*(-1)(T+2)^(-2)
NOTE: QUOTIENT RULE GIVES SAME RESULT.
F'(-1)=-4/1^2=-4
========
1/(X+1)
DERIVATIVE HAS DENOMINATOR OF (X+1)^2
NUMERATOR IS -1
-1/(X+1)^2
G(-1)=UNDEFINED.
