Answer:
20
Step-by-step explanation:
The given relation can be written as the 2-step linear equation ...
(1/3)n +2 1/3 = 9
n +7 = 27 . . . . . . . . . step 1: multipy by 3 (makes the coefficient = 1)
n = 20 . . . . . . . . . . . step 2: subtract 7 (separates variable from constant)
The number is 20.

<em>Additional comment</em>
Usually it is convenient to do the two steps in the opposite order: get the variable term by itself, then make its coefficient 1. Here, we chose the order we did because it eliminated fractions from the problem, which is often a step you'd like to do first.

A) the x-values on the graph are [-2, 4].
all the x-values of the graph are the Domain of the function of the graph. they are found by projecting the graph to the x-axis. check the yellow line in the first picture.
b) all the possible outputs of g are [-1, 3].
all the possible outputs of g, are the Range of g. These are found by projecting the graph to the y-axis. check the red line in the second picture.
c) -1 , 0, 1, 2, and 3 are only a few values in the Range. The range is [-1, 3].
d) we will sketch a graph whose domain is [-2, 4] and range is [-1, 3]. check picture 3
F(-3)=(-2)*(-3)-4=6-4=2
F(-2)=(-2)*(-2)-4=4-4=0
F(-1)=(-2)*(-1)-4=2-4=-2
