The graph below shows a function $f$ . On the interval $[0, 3]$ , the graph goes from $f(0) = 2$ up to $f(3) = 8$ . On the interval $[3, 6]$ , the graph goes from $f(3) = 8$ down to $f(6) = 1$ . On which interval is $f$ decreasing?

$[0, 3]$ because $f(x)$ is positive there.

$[3, 6]$ because $f(x)$ gets smaller as $x$ increases.

$[0, 3]$ because $f(x)$ goes up to 8, which is a large number.

The function is not decreasing anywhere because all values are positive.
