Question

Calculate the average rate of change of the function represented by the table between x = 1 to x = 3, and tell what the average rate represents. (Table below)

Answer 1

The average rate of change is just the slope.

Answer 2

\[\text{average rate of change}=\frac{y(3)-y(1)}{3-1}\]
\(y(x)\) is the value of \(y\) at a given \(x\) value.

Answer 3

\[\frac{ 800 - 900 }{ 3 - 0 }?\]

Answer 4

It's y1 - y2 over x1 - x2

Answer 5

So 900 - 850 over 0 - 1

Answer 6

over 50 over -1
which is -50, which is our slope. Which is also our speed. :D

Answer 7

The question says x1, and x3 though?

Answer 8

It's on the same line, so it really doesn't matter.

Answer 9

Okay! :D Glad I became a fan of you. xD

Answer 10

850 - 750 over 1 - 3
100 over -2
100 / -2
-50

Answer 11

Thanks again.
