Definition of Derivative...2

Calculus
Section 2.8

 

answers for derivatives are correct

still ask you to state the domain of the function and the domain of its derivative

 

correct

 

Thank you. How is the range found with and without a graph?

 

26.

f(t)=t^3-5t+1

range:
R (all real numbers)

f'(t)=3t^2-5
range:
{f element R : f>=-5}

28.
f(v)=v/(v+2)

range :



range:
{y element R : y>0} (all positive real numbers)

 

No image in your reply. By the way, I posted enough questions in two forums other than Calculus for you to play with during the week. Enjoy. Please, follow my directions.

 

for 28 image was
{f element R : f ≠ 1 }

 

Ok. Check out the Geometry and Trigonometry forum for new threads.
