Answer:

Increasing on (-4, 2) and (1, 3); Decreasing on (-2, 1).

Step-by-step explanation:

The function is said to be increasing function if as the value of x increases, then the value y also increases.

The function as a decreasing function if as the value of x increases, y decreases or vice-versa.

And the function is said to be constant if as x increases the value of y remains the same or vice-versa.

Here, Function is increasing from (-4, -4) to (-2, 4.5) and from (1, 0) to (2, 8)

and function is decreasing from (-2, 4.5) to (1, 0).

Answer:

a) $42,580

b) $43,900

Step-by-step explanation:

Recall, "mode" refers to the value which occurs most frequently.

In this case, the question says that there are 2 modes,

this means $34,000 and $50,500 both share the spot for the most frequently appearing salary.

because there are only 5 employees (and hence 5 salaries), the only possible way that there are two modes is if there are two of each mode, leaving only the last salary unknown.

i.e  if we list the 5 salaries (in no particular order)

$34,000   $34,000  $50,500   $50,500   $ x

where x is the 5th unknown salary.

Given that the mean is $42,100

Then (34,000 + 34,000 + 50,500 + 50,500 + x) / 5 = 42,100

solving for x gives x = $41,500

Now we know all the values, we can rearrange them in increasing value:

$34,000   $34,000  $41,500   $50,500   $50,500  

from this, we can see that the median salary is $41,500

Given that the median salary gets a $2400 raise,

the new median salary = $41,500 + $2400 = $43,900 (Ans for part b)

new mean salary,

= ($34,000  + $34,000 + $43,900 +  $50,500  + $50,500  ) / 5

= $42,580 (answer for part a)
