Step-by-step explanation:

this is only asking about the functional values.

in what intervals are the functional values going up (when increasing x from left to right), and in what intervals is the functional value going down (again, when increasing x from left to right) ?

and so we see in the graph,

it is increasing (y-values are going up) in

(-infinity, -1], (2, +infinity)

it is decreasing (y- values are going down) in

(-1, 2]

please consider the used types of brackets.

"(", ")" means the corresponding interval end is NOT included.

"[", "]" mags the corresponding interval end is included.

"infinity" is only a concept and not a value, so it can never be included.

and I wanted the intervals to have no overlap. so, I included "-1" in one and excluded it in the connecting interval. the same for "2".

but if your teacher prefers to have the interval ends overlapping, then please change these brackets to "["as needed. it all depends on what your teacher defined for you.

Given: 44 - 2(3x + 4) = -18Prove: x = 9

Answers

Substitute 9 as x in the given function:
44-2(3(9)+4)=-18
Now check and see if the statement it true and simplify.
44-2(27+4)=-18
44-2(31)=-18
44-62=-18
-18=-18
You can see this is true !!
