# Thread: Consider the function below......

1. ## Consider the function below......

(A) f(x) = ln(x4 + 27),
(B) g(x) = 3x2/3x

(a) Find the interval of increase and Find decrease.
(b) Find the local minimum value.
Find the interval where the function is concave up and concave down.

2. ## Re: Consider the function below......

have you solved for f'=0 and g' = 0?
