Answer:
-8 ≤ x ≤ - 6
2 ≤ x ≤ 6
Step-by-step explanation:
Increasing part of the function can be easily determined from the graph.
Note that increasing function means for each successive values of 'x', the values of 'y' keep increasing.
From the graph, we see that the function is increasing in the interval
Between -6 and -4, the graph is constant and takes the value 4.
After that it decreases till x = -2 until it becomes a constant function again on x = 2.
Then, it again increases from x = 2 till x = 6. This is represented by the interval
.
Then it again decreases.
So, OPTION A and C are the answers.
To solve this problem we can use system of equations.
First equation can be
321=x+y
where x - ppl between 4-17 and y - adult
second equation can be as follows
1590=6*y+4*x
So we have
From first equation we get value of x in times of y
x=321-y
Now we can substitute it into second eq.
1590=6y+4(321-y)
now simply if
1590=6y+1284-4y /-1284 both sides
306=2y /:2 divide both sides by 2
y=153
Now we can back substitude
x=321-153
x=168
So we get result
