Answer:
(f+g)(x) = x^3 - 3x + 2
Step-by-step explanation:
Find (f+g)(x) by adding together f(x) = -3x + 2 and g(x) = x^3:
(f+g)(x) = -3x + 2 + x^3, or, in standard form,
(f+g)(x) = x^3 - 3x + 2

Answer:
A. 11
Step-by-step explanation:
The average rate of change of the given function over the interval [2,6] is simply the slope of the secant line connecting the point (2,f(2)) and (6,f(6)).
This implies that, the average rate of change over [2,6]
![=\frac{f(6)-f(2)}{6-2}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bf%286%29-f%282%29%7D%7B6-2%7D)
![=\frac{f(6)-f(2)}{4}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bf%286%29-f%282%29%7D%7B4%7D)
From the table f(6)=71
Since we want the average rate of change to be 15, we have;
![15=\frac{71-f(2)}{4}](https://tex.z-dn.net/?f=15%3D%5Cfrac%7B71-f%282%29%7D%7B4%7D)
This implies that;
![4\times15=71-f(2)](https://tex.z-dn.net/?f=4%5Ctimes15%3D71-f%282%29)
![60=71-f(2)](https://tex.z-dn.net/?f=60%3D71-f%282%29)
![60-71=-f(2)](https://tex.z-dn.net/?f=60-71%3D-f%282%29)
![-11=-f(2)](https://tex.z-dn.net/?f=-11%3D-f%282%29)
![11=f(2)](https://tex.z-dn.net/?f=11%3Df%282%29)
The correct choice is A.
