Which of the following values are in the range of the function graphed below? check all that apply. ! a) 1 b) 0 c) -1 d) 6 e) 2 f) -2

The only answer is choice D) 6

Recall that the range is the set of possible y output values of a function. In other words, its the list of y coordinates for every point on the function curve. 

In this case, the horizontal line has EVERY point on it with a y coordinate of y=6. Two such points are (0,6) and (2,6). No other y value is possible. No matter what x value we plug in, the output is always y = 6

Side Note: the domain appears to be from x = -3 to x = 5
