Question 1042989
 how do I write an exponential function of a graph passing through these two points 1,6 and 1,3 ?
Something wrong here, when x=1, y=6. The same equation cannot have x=1, y=3
:
an equation that satisfies x=1, y=6:  
An exponential function y = 3*2^x, looks like this 
{{{ graph( 300, 200, -2, 5, -8, 50, 3*2^x) }}}
:
an equation that satisfies x=1, y=3:  
An exponential function y = 1.5*2^x, looks like this 
{{{ graph( 300, 200, -2, 5, -8, 50, 1.5*2^x) }}}
