Absolute Extrema 43B4A3
1. **Problem Statement:**
We are given a function defined on the interval $[0,2[$ and asked to determine whether it has an absolute minimum and/or maximum value on this interval.
2. **Understanding the Interval:**
The interval $[0,2[$ means $x$ ranges from 0 inclusive to 2 exclusive. So the function is defined at $x=0$ but not at $x=2$.
3. **Observing the Graph:**
- At $x=0$, the function value is $f(0) = 2$.
- At $x=1$, the function value is $f(1) = 0$.
- As $x$ approaches 2 from the left, the function value decreases steeply toward $-2$ but the function is not defined at $x=2$.
4. **Absolute Maximum:**
The highest value on the interval is at $x=0$ with $f(0) = 2$. Since $0$ is included in the domain, the function attains its absolute maximum value of 2.
5. **Absolute Minimum:**
The function values decrease toward $-2$ as $x$ approaches 2, but since $x=2$ is not included, the function never actually attains $-2$. It gets arbitrarily close but does not reach it.
Therefore, there is no absolute minimum value on $[0,2[$.
6. **Conclusion:**
The function has an absolute maximum value but no absolute minimum value on the interval $[0,2[$.
**Final answer:** (c) has absolute maximum value but not absolute minimum value
