Please help 30 points I graphed the seamos out already and the question are in a separate picture

On interval f(x) is increasing =  

On interval f(x) is decreasing =

Step-by-step explanation:

The given function:

The graph of the function is attached below

In graph , function is increasing till point (-2,4) or x=-2 and then it is decreasing.

So f(x) is increasing in and decreasing in

So, On interval f(x) is increasing =  

On interval f(x) is decreasing =

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

answer: about 22.67
