ok so I have three questions I am struggling with.
1.) The table of values represents a polynomial function f (x).
How much greater is the average rate of change over the interval [7, 9] than the interval [4, 6]?
x f(x)
4 358
5 690
6 1178
7 1852
8 2742
9 3878
2.) What is (f+g)(x)?
f(x)= x3 - x
g(x)= x3+2x2-10
3.)
What is (f⋅g)(x)?
f(x)=x2+2x−6
g(x)=x4+3
