question
the graph of $y = f(x)$ is shown below. find all values of $x$ for which $f(x) > 0$.
answer attempt 1 out of 2

Explanation:

Step1: Identify x-intercepts

The graph crosses the x-axis at $x=0$ and $x=4$.

Step2: Find regions where $f(x)>0$

The parabola opens upward, so it is above the x-axis (where $f(x)>0$) when $x<0$ or $x>4$.

Answer:

$(-\infty, 0) \cup (4, \infty)$
