Answer:

The average rate of change over the interval is 120

Step-by-step explanation:

For a function f(x) the average rate of change over an interval [a,b] is given as;

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

in this case, a is 2 and b is 4

f(b) is 256 and f(a) is 16

Substituting these values in the equation for rate of change, we have;

(256-16)/(4-2) = 240/2 = 120

Solve for n<br><br> -19=-8+n

Answer: $\textsf{n = -11}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{-19 = -8 + n}$

Find: $\textsf{Solve for n}$

Solution: In order to solve for n we need to add 8 to both sides which would cancel -8 on the right side and isolate n giving us the value of n.

<u>Add 8 to both sides</u>

$\textsf{-19 + 8 = -8 + 8 + n}$

$\textsf{-19 + 8 = n}$

$\textsf{-11 = n}$

Therefore, the final answer would be that n is equal to -11.
