Using the graph calculator to graph the function f(x)=-√x. which list contain three points that lie on the graph of the function? (-9,,,1) (1,,,3) (-9,-,-,-1) (1,-,-,-3)

The list of points that lie on the graph of the function is:

                (1,-1),(4,-2),(9,-3)  

The square root function f(x) is given by:

We know that the domain of the square root function is x ≥ 0

and when x ≥ 0

then √x ≥ 0

Hence,

This means that the list of points must have x-coordinate as non-negative value and y-coordinate as non-positive value.

Now when x=1

we have:

when x=4 we have:

and when x=9 we have:

Hence, the points are:

(1,-1) , (4,-2) and (9,-3)

By plotting the graph of this function we may check the point.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
