Exercise 5.1 One of these is not the name of a pattern-book function. Which is it?

gaussian       tangent       logarithm       sigmoid      

question id: not-pattern-book

Exercise 5.2 For each of these pattern-book functions, say whether the range includes negative numbers.

1. proportional

yes       no      

question id: pattern-ranges-proportional

2. square

yes       no      

question id: pattern-ranges-square

3. reciprocal

yes       no      

question id: pattern-ranges-reciprocal

4. gaussian

yes       no      

question id: pattern-ranges-gaussian

5. sigmoid

yes       no      

question id: pattern-ranges-sigmoid

6. sinusoid

yes       no      

question id: pattern-ranges-sinusoid

7. exponential

yes       no      

question id: pattern-ranges-exponential

8. logarithmic

yes       no      

question id: pattern-ranges-logarithmic

Exercise 5.3 Which pattern-book function corresponds to every increasing growth such that each increase in the input by a fixed amount leads to a doubling of the function output?

logarithmic       exponential       square       reciprocal      

question id: doubling-reading

Exercise 5.4 Which of these is an exponential function: $f(x)\equiv 2^x$ or $g(x)\equiv x^2$? (Hint: You should be able to figure this out from the reading just based on the exponents in the respective function formulas.)

Both       Neither       f() only       g() only      

question id: exp-or-power
