Question 1: Which is false about the asymptote of a logarithmic function:

a) The asymptote restricts the domain of the function

b) If a log function has a base of 2 and an asymptote of x=a then the interval of increase will be (2, positive infinity)

c) If a log function has a base of 1/2 and an asymptote at x=a, the interval of decrease is {x|x>a, xR}

d) All logarithmic functions have asymptotes

Question 2: What is true about exponential functions with a base between 0 and 1?

a) The y intercept is 1

b) they are always increasing

c) the range is yR

d) they are undefined when x is 0.
