# 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.

Somebody help me, please?

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

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