Question 173775
Plot the graph of the following functions: 
Plot points, then connect the points with a smooth curve:
f(x)=7^x
Points: (-1,1/7), (0,1), (1,7), (2,49) etc
{{{graph(400,300,-10,10,-10,10,7^x)}}}
----------------------------------------------
f(x)=4^x-3
Points: (-1,-11/4), (0,-2), (1,1), (2,13) etc
{{{graph(400,300,-10,10,-10,15,4^x-3)}}}
----------------------------------------------
f(x)=(1/5)^x
Points: (-1,5), (0,1), (1,1/5), (2,1/25),etc
{{{graph(400,300,-10,10,-10,7,(1/5)^x)}}}
-----------------------------------------------
f(x)=log(3x)
Points: (1,0.4771), (2,0.7782), (3,0.9542) etc
{{{graph(400,300,-5,5,-5,2,ln(3x))}}}
