Question 867048
given: {{{y=o.6^x}}} for  ...I believe should be {{{-4<=x<=4}}} not {{{4<=x<=4}}} as posted above

a.

make first table

{{{x}}}|{{{y}}}
{{{-4}}}|{{{7.7}}}
{{{-3}}}|{{{4.6}}}
{{{-2}}}|{{{2.8}}}
{{{-1}}}|{{{1.7}}}
{{{0}}}|{{{1}}}
{{{1}}}|{{{0.6}}}
{{{2}}}|{{{0.4}}}
{{{3}}}|{{{0.2}}}
{{{4}}}|{{{0.13}}}


{{{ drawing(600, 600, -4, 4, -4, 4,locate(-1.4,2,p(-1.4,2)), circle(4,0.13,0.1),circle(3,0.2,0.1),circle(2,0.4,0.1),circle(1,0.6,0.1),circle(0,1,0.1),circle(-1,1.7,0.1),circle(-2,2.8,0.1),circle(-4,7.7,0.1),circle(-3,4.6,0.1),graph( 600, 600, -4, 4, -4, 4, 0.6^x,2)) }}} 

b. use the graph to solve the equation {{{ (0.6)^x = 2}}}

as you can see, for {{{x = -1.4}}} we have {{{ (0.6)^x = 2}}}....the green line that I put on a graph shows you the point 
({{{-1.4}}},{{{2}}})
