APFIVE Absolute Extrema on a Closed Interval
Consider the function $$f(x)=x^3-6*x^2+9*x+2$$ on the interval $$[2,5]$$. Using the candidate’s test, determine the absolute minimum and maximum values of $$f(x)$$ on this interval.
| x | f(x) |
|---|---|
| 2 | 4 |
| 3 | 2 |
| 5 | 22 |
A
Absolute minimum: $$2$$ at $$x=3$$; Absolute maximum: $$22$$ at $$x=5$$.
B
Absolute minimum: $$2$$ at $$x=3$$; Absolute maximum: $$22$$ at $$x=3$$.
C
Absolute minimum: $$22$$ at $$x=5$$; Absolute maximum: $$2$$ at $$x=3$$.
D
Absolute minimum: $$4$$ at $$x=2$$; Absolute maximum: $$22$$ at $$x=5$$.
