Question

The graph represents f(x) = x + 3

On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is an open circle. The right end of each segment is a closed circle. The left-most segment goes from (negative 5, negative 1) to (negative 4, negative 1). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (1, 5) to (2, 5).

What is f(−2.2)?

-2
0
1
2

Answer 1

The answer to this question is (-2,0)

Answer 2

The answer is C, 1.

Explanation:

The answer is simple. You round up to the nearest whole number (cant be a negative,) and it can't be a 0. Therefore, you get 1.
