Question

F= ((-4,-1),(-3,-1),(-2,-3),(3,0))G=((5,3),(4,-1),(-2,-4),(-4,-5)Find (f+g)(-2)

Answer 1

Given,

$\begin{gathered} F=\mleft(-4,-1\mright),\mleft(-3,-1\mright),\mleft(-2,-3\mright),\mleft(3,0\mright) \\ G=\mleft((5,3),(4,-1),(-2,-4),(-4,-5)\mright) \end{gathered}$

Now, apply the given mapping

$\begin{gathered} (f+g)(-2)=f(-2)+g(-2) \\ =-3-4 \\ =-7 \end{gathered}$

So,the required answer is,

$(f+g)(-2)=-7$
