Question

Hi, can you help me find the critical numbers of this function?
f(t)=3t^(2/3)+t^(5/3)

Thank you!

Answer 1

did you take the derivative?

Answer 2

you should get
\[\frac{5t+6}{3\sqrt[3]{t}}\]

Answer 3

zero is one critical point, other one set the numerator equal to zero and solve

Answer 4

Thank you so much! I found it. -1.2 or -6/5
