Let's analyze the graphs one by one to estimate the x-intercepts and y-intercepts.

11.

• X-intercept: The graph crosses the x-axis around $x = 6$.
• Y-intercept: The graph crosses the y-axis around $y = -4$.

12.

• X-intercept: The graph crosses the x-axis around $x = 3$.
• Y-intercept: The graph crosses the y-axis at $y = 2$.

13.

• X-intercepts: The graph (a parabola) crosses the x-axis at two points, around $x = -2$ and $x = 2$.
• Y-intercept: The graph crosses the y-axis at $y = -4$.

14.

• X-intercepts: The graph (another parabola) crosses the x-axis at two points, around $x = 0$ and $x = 6$.
• Y-intercept: The graph crosses the y-axis at $y = 4$.

Tip:

Remember that x-intercepts occur where $y = 0$, and y-intercepts occur where $x = 0$. This concept is fundamental for graph interpretation!
