Question
- identify where the following graph is positive or negative
if it is positive or negative on more than one interval us u in between intervals
positive: $square \cup \square$
negative: $square$
Step1: Identify x-intercepts
The graph crosses the x-axis at $x=-4$ and $x=-2$.
Step2: Find positive intervals
The parabola opens upward, so it is above the x-axis (positive) when $x < -4$ or $x > -2$. In interval notation, this is $(-\infty, -4) \cup (-2, \infty)$.
Step3: Find negative interval
The parabola is below the x-axis (negative) between the two intercepts, so when $-4 < x < -2$. In interval notation, this is $(-4, -2)$.
