Question 1153045
Just looking at #5, the points are  (0,2), (1,8), and (2,32).


{{{2=a*b^0}}} using first point
{{{a*1=2}}}
{{{a=2}}}


Trying the second point
{{{8=2*b^1}}}
{{{8=2b}}}
{{{b=4}}}


To CHECK with the third point
{{{32=2*4^2}}}
{{{32=2*16=32}}}


Now just fill the equation for variables "a" and "b", for this g(x) function  (as the exercise function is labeled):
{{{highlight(g(x)=2*4^x)}}}
