Answer 1

First we have to find the y value for each value, so substitute 8 and 14 into the equation first

Answer 2

ok

Answer 3

So lets do
\(\sqrt{(8)-4}\)
and
\(\sqrt{(14)-4}\)

Answer 4

2 and 10

Answer 5

The first one is right, the second one make sure you simplified well
\(\sqrt{14-4}\\
=\sqrt{10}\)
But
\(\color{red}{\sqrt{10}\neq 10}\)

Answer 6

ok

Answer 7

3.16?

Answer 8

Right, so we have
(8,2) and (14,3.16)
To find the average rate of change we can do
\(\frac{y_2-y_1}{x_2-x_1}\)

Answer 9

alright, which leaves

Answer 10

Do you know how to substitute that? x'D
Assuming that (8,2) is the first coordinate and (14,3.16) was the second point
