Answer 1

From the graph, the function has a maximum of 4 at x=3.

The slope of the graph is positive in the interval (-∞, 3).

Hence, the function is increasing in the interval (-∞, 3).

The slope of the graph is negative in the interval (3, ∞).

Hence, the function is decreasing in the interval (3, ∞).
