Reading question 14.3 The general form of a number written in scientific notation is \(a \times 10^b\).

  1. What does convention say about the possible range of \(a\), ignoring the sign?

It should be less than 0 but no less than -1.

It should be less than 1 but no less than 0.

It should be less than 10 but but no less than 1.

It should be an integer, that is, a “whole number.”

It can be any number at all.

question id: scientific-notation-1

  1. What does restriction is placed on the value of \(b\)?

It should be less than 0 but no less than -1.

It should be less than 1 but no less than 0.

It should be less than 10 but but no less than 1.

It should be an integer, that is, a “whole number.”

None. It can be any number at all.

Reading question 14.4  

  1. What does it mean to graph data on “semi-log” axes?

question id: log-axes-1

Ordinary axes, not including logarithmic transformation, are sometimes called “linear axes.”

  1. Which of these is a graphics form considered in the Reading which is neither “semi-log” nor “linear.”
uni-log       dual-log       demi-log       log-twice       log-log
