Answer 1

@jim_thompson5910 please read my message

Answer 2

f(x) is concave downward when f ' (x) is decreasing (so when the tangent slopes on f ' (x) are negative)

Answer 3

so, (1,2)???

Answer 4

It is a continuation of your earlier question where you were asked to identify the points of inflection for the same graph. What were your points of inflection?

Answer 5

the first piece of the overall answer is (0,1) because the f ' (x) function is decreasing from x = 0 to x = 1.

Answer 6

The tangent lines on f ' (x) have negative slopes in this interval.

Answer 7

On what interval(s) is f concave upward?

Answer 8

2,4,6,8 @aum
