2. Can you check my work?
f(10)=0.08*10^3+10^2+0.26
80+100+10+0.26
=190.26

6. 1: Polynomial of 4 terms.
2: Since n is odd and a is positive, the end behavior is down and up.
3: (graph that goes up right and up through -2, and 2).
4: -137
5: f(x)=x^3-x^2-4x+4
6: The relative maximum is at (-3, 19), and the relative minimum is at (1, -13).
7: No solution.
8: 3x^2-6x+20, R -62
9: -3x^2-x-5
10: 24 ft^3
11: (Essay) f(10)=0.08*10^3+10^2+0.26
80+100+10+0.26
=190.26
