as the plot.
(2) Let
A =
8 1 6
3 5 7
4 9 2
B =
2 7 6
9 5 1
4 3 8
(a) Calculate AB.
(b) Calculate A times B componentwise.
(3) Let f(x) = −6x + 50, g(x) = p
|25x + 4|, h(x) = x

. Plot these using
input values from -10 to 10 with 200 equally spaced points. All functions
should be a different color and style (use the command ”help plot” to find
the plot options for different colors and styles.) Be sure to add a legend to
your plot.
Please only submit the pertinent parts of the diary. I don’t need to see all your
mistakes. You can edit the diary after you double click on it. Make sure your
homework includes your name, section number, and lab number on the top of each
submission.
