Answer:

A) -15

Step-by-step explanation:

The average rate of change of f(x) on interval [a, b] is given by ...

(f(b) -f(a))/(b -a)

Here, you have ...

f(x) = -2^x +70

[a, b] = [2, 6]

so the average rate of change is ...

(f(6) -f(2))/(6 -2) = ((-2^6 +70) -(-2^2 +70))/4 = (-64 +4)/4 = -16+1

average rate of change = -15

Answer: My bad if I butchered any answers. It was hard to read tbh

Step-by-step explanation:

D.) You can only factor out an x here. So you'd get: $x(x^2-2x+4)$

E.) You can factor out a 3x^2y to get: $3x^2y(2-x)$

F.) You can factor out a 3xy to get: $3xy(y+3x-2)$

G.) You can factor out a -4ab to get: $-4ab(a-4b+2)$
