Zhang walks in a straight line from the trail head at (0,0). He travels at an average rate of 3 mi/h in the direction 30° west of north. What are the coordinates of Zhang's location, relative to the trail head, after 4 hours

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

the radius is 2 times the diameter.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
