The step function f(x) is graphed. On a coordinate plane, a step graph has horizontal segments that are each 2 units long. The left end of each segment is a closed circle. The right end of each segment is an open circle. The left-most segment goes from (negative 3, negative 3) to (negative 1, negative 3). Each segment is 2 units higher and 2 units farther to the right than the previous segment. The right-most segment goes from (3, 3) to (5, 3). What is the value of f(−1)? -3 -1 0 1

Given : The step function f(x) is graphed

step graph has horizontal segments that are each 2 units long

To Find : Domain of f(x)

f(-1)

Solution:

The left-most segment goes from (- 3, -3) to (-1, -3).

The right-most segment goes from (3, 3) to (5, 3).

The left end of each segment is a closed circle.

Hence Left most point  ( - 3 , - 3)    

-3 is included

The right end of each segment is an open circle

Hence right most point ( 5 , 3)

5 is not included

Hence Domain  of f(x) is     - 3 ≤ x < 5

{x| –3 ≤ x < 5}

f(-3) =  - 3

f(-1)  = - 1

f(1)  = 1

f(3) = 3
