Question

All points of the step function f(x) are graphed.

What is the range of f(x)?

A. −3, −2, −1, 0, 1
B. −2, −1, 0, 1
C. all real numbers such that −3 < y ≤ 1
D. all real numbers such that −2 < y ≤ 1

please help asap thank you so much

Answer 1

The range of a function is which values it can take over a given domain

The range of the step function is the y-values

y: -2,-1,0,1

Thus the range of f(x) is -2,-1,0,1.

Answer 2

B. −2, −1, 0, 1

Explanation:

The range of a function is the set of y-values.

In this graph, we can see that the points hit the y-values -2, -1, 0 and 1; this is the range of the function.
