Your class is having a class picture taken on the lawn. The photographer is
positioned 14 feet away from the center of the class.
The photographer turns 50° to look at either end of
the class.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

table 3 represents a direct variation function. : )
