For the next 4 lessons, we will teach extra content about exponents and logarithms.

Today we go over the basic exponential functions and introduce logarithms.

For homework, get these two pages: Page 1, Page 2

From Page 1, 13.1.1 – 13.1.5; From Page 2, 13.2.1 – 13.2.4

We focus on speed-time graphs, how to read a speed-time graph, how to calculate the distance, how to draw a distance-time graph from a speed-graph, etc.

There are some homework that is about speed-time graph, please use last class’s homework sheets and do or redo the parts about speed-time graph.

We will have a quick review of statistics and probabilities next time. We will have our final exam on 6/18.

Here are some more homework:

Page 8, Page 9, Page 10, Page 11

#19, #20, #22, #23, #24, #25.

We study tables, charts, and graph, in particular we study distance-time graphs and speed-time graphs.

In our earlier classes (Math 7), students should have learned the basics of reading, interpreting and graphing of tables, charts, and graphs, as well as working with distance-time graphs.

So we focus on study speed-time graphs which can contain more information about the motion of an object than that of a distance-time graph.

With a speed-time graph, we can calculate acceleration, as well as calculating distance traveled, which is the area under the speed time graph.
