Question 172076
Process:

Pick a value for {{{x}}}.  Substitute this value for x in your function and do the arithmetic to determine the value of {{{f(x)}}}.  Then plot the point ({{{x}}},{{{f(x)}}}).


Repeat.


You only have to plot 2 points for each of problems 1, 2, and 3 because they all graph as straight lines -- and two points determine a line.  But number 4 is a logarithmic curve.  Use your calculator.  Since the base is not specified, you must assume base 10 logs.


Advice for selecting values of {{{x}}} for problem 4:


Make sure that {{{3x>0}}} for all of your selections:  The domain of {{{log(b,(x))}}} is {{{x>0}}}


The graph will intersect the x-axis at {{{x=1/3}}} because {{{log(b,(1))=1}}} -- always.


Make sure you pick a couple of points such that {{{3x < 1}}}.


Pick a couple of points such that {{{3x>10}}}


Finally, select several points such that {{{1 < 3x < 10}}}
