Question 1127673
model for {{{y=a*b^x}}}


Plug in the point coordinates
{{{system(ab^(-1)=4/3,cross(ab^4=304),ab^4=324)}}}


{{{(ab^4)/(ab^(-1))=324/(4/3)}}}


{{{b^5=(3*324)/4}}}


{{{cross(b^5=228)}}}
{{{b^5=243}}}


{{{cross(b=2.96201)}}}
{{{highlight(b=3)}}}


Using either original equations,  {{{highlight_green(a=4)}}}.
