Answer 1

A. y

General Formulas and Concepts:

Algebra I

• Range is the set of y-values that are outputted by function f(x)

Explanation:

According to the graph, we can see that we have a horizontal asymptote at y = 4. Our y-values stretch from negative infinity to the horizontal asymptote.

∴ our answer would be A.
