Quadratic Intercepts 911674
1. **State the problem:** Find the coordinates where the graph of the quadratic equation $$y = (4 - x)(x + 5)$$ crosses the x-axis and y-axis.
2. **Find x-intercepts:** The graph crosses the x-axis where $$y = 0$$.
Set $$y = 0$$:
$$0 = (4 - x)(x + 5)$$
This product is zero if either factor is zero:
- $$4 - x = 0 \Rightarrow x = 4$$
- $$x + 5 = 0 \Rightarrow x = -5$$
So the x-intercepts are at points:
- $$(4, 0)$$
- $$(-5, 0)$$
3. **Find y-intercept:** The graph crosses the y-axis where $$x = 0$$.
Substitute $$x = 0$$ into the equation:
$$y = (4 - 0)(0 + 5) = 4 \times 5 = 20$$
So the y-intercept is at point:
- $$(0, 20)$$
**Final answer:**
- x-intercepts: $$(4, 0)$$ and $$(-5, 0)$$
- y-intercept: $$(0, 20)$$
