Maggie and Emma race each other along a straight running track. Maggie starts some distance ahead of Emma. The graph describes the race. What is an appropriate domain for Emma line?

Step-by-step explanation:

See attachment for graph

Required

Determine the domain of Emma's line

First, we calculate the equation of Emma's line

Start by calculating the slope (m)

Where the x's and y's represent corresponding values of x and y on Emma's line

Emma's line is represented by the thick line.

So, we have:

becomes

The equation is then calculated using:

Where

So:

To get the domain, we have the following:

x represents time and x can not be negative.

So, the least value of x is: x = 0

The maximum value of x is unknown.

So, the maximum value of x is: x = +infinity

Hence, the domain is

33

step-by-step explanation: g=6

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
