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 =

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
