Answer: Choice C.
$f(x) \le 1$

=========================================================

Reason:

The f(x) represents the y output, and the range is the set of all possible y outputs of a function.

The largest y can get is y = 1, which is at the highest point of the graph, aka the vertex.

We can have y = 1 or y < 1.

Therefore, the range is
$y \le 1$ which translates to
$f(x) \le 1$
