Linear Interval
1. The problem is to analyze the function $f(x) = 2x - 1$ on the interval $[-3, 2]$.
2. This is a linear function with slope 2 and y-intercept $-1$.
3. To find the values at the interval endpoints:
- At $x = -3$, $f(-3) = 2(-3) - 1 = -6 - 1 = -7$
- At $x = 2$, $f(2) = 2(2) - 1 = 4 - 1 = 3$
4. Since the slope is positive, the function is increasing over the interval.
5. Therefore, the minimum value on $[-3, 2]$ is $-7$ at $x = -3$ and the maximum value is $3$ at $x = 2$.
6. Summary:
- Domain: $[-3, 2]$
- Minimum: $f(-3) = -7$
- Maximum: $f(2) = 3$
- Linear increasing function
