Question

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)?
a.)-3
b.) -1
c.) 0
d.) 1

Answer 1

Answer:

b. -1

Step-by-step explanation:

(-3,-3) to (-1,-3)

(-1,-3+2) to (-1+2,-3+2)

(-1,-1) to (1,-1)

Since the left/lower end of the domain is included, f(-1) is -1
