SOLUTION
STEP 1: Write the given functions
[tex]\begin{gathered} f(x)=2x^2+3x-1 \\ g(x)=-x \end{gathered}[/tex]STEP 2: Find f(-1)+g(-1)
We find f(-1) first,
[tex]\begin{gathered} Substitute\text{ }-1\text{ }for\text{ }x\text{ }inf(x) \\ 2(-1)^2+3(-1)-1=2-3-1=2-4=-2 \end{gathered}[/tex]We find g(-1),
[tex]\begin{gathered} g(x)=-x \\ substitute\text{ -1 for x in g\lparen x\rparen} \\ g(-1)=-(-1)=1 \end{gathered}[/tex]Find the required function,
[tex]f(-1)+g(-1)=-2+1=-1[/tex]Hence, the answer is -1
