Question 736435
If the domain is { {{{0}}}, {{{2}}}, {{{-6}}} } (means all {{{x}}} values ), you will find the range of {{{y = -2x + 3}}} if you substitute {{{x}}} values in given function:


if {{{x=0}}}...=>...{{{y = -2*0 + 3}}}...=>...{{{y =  3}}}

if {{{x=2}}}...=>...{{{y = -2*2 + 3}}}...=>...{{{y =-4+  3}}}...=>...{{{y =-1}}}

if {{{x=-6}}}...=>...{{{y = -2*(-6) + 3}}}...=>...{{{y =12+  3}}}...=>...{{{y =15}}}

so, the range is: { {{{3}}}, {{{-1}}}, {{{15}}} }
