Let f(x)=−x√3 . what is the average rate of change of f(x) from 8 to 64?
−1/28
1/28
−28
28

Step-by-step explanation:

The given function is

The average rate of change of this function is the slope of the secant line connecting the points (64,f(64)) and (8,f(8));

We substitute the functional values into this function to obtain;

This simplifies to;

the answer is c just got it on ed

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
