Determine where the function is increasing, decreasing, and constant.

Step-by-step explanation:

How does y change as x increases over a range?

As x increases from -6 to -4, y decreases from 0 to -7

It is a decreasing function in this range and for ranges less than x = -6 as well as the slope is nearly constant

As x increases from -4 to 0, y increases from -7 to 4

It is an increasing function in this range.

For x increasing from zero, y becomes less and less

It is a decreasing function in the range larger than x = 0

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
