Question 644341
{{{f(x)=3x^2+2}}}, if {{{x<=-1}}}....I guess you are given {{{f(-2)}}} is the value of {{{x}}} because {{{-2<-1}}}

{{{f(-2)=3(-2)^2+2}}}


{{{f(-2)=3*4+2}}}


{{{f(-2)=12+2}}}


{{{f(-2)=14}}}



{{{f(x)=-x-4}}}, if {{{x>-1}}}...........let's take {{{x=0}}}

{{{f(0)=-0-4}}}

{{{f(0)=-4}}}
