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 =

-1/4 > -1 2/3. -1/4 is greater than -1 2/3 because it is closer to 0 on the number line.

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
