Answer
$(G-F)(7)= 5$
$(G-F)(3)= -1$
Work Step by Step
RECALL:
$(G - F)(x) = G(x) - F(x)$
Using the rule above gives:
$(G - F)(7) = G(7) - F(7)$ and $(G- F)(3)=G(3)- F(3)$
The graph shows that:
$F(7)=-1$; $F(3)=2$
$G(7)=4$; $G(3)=1$
Thus, using the values above give:
$(G-F)(7)=G(7) - F(7)=4-(-1) = 4+1 = 5$
$(G-F)(3)=G(3) - F(3) = 1-2=-1$
