Work Step by Step
We have:
$f(0)=2$
$f(1)=3$
$f(2)=1$
$f(3)=2$
$g(0)=-1$
$g(1)=0$
$g(2)=0.5$
$g(3)=0$
Compute $h(x)=(f+g)(x)$ for the given points:
$h(0)=(f+g)(0)=f(0)+g(0)=2+(-1)=1$
$h(1)=(f+g)(1)=f(1)+g(1)=3+0=3$
$h(2)=(f+g)(2)=f(2)+g(2)=1+0.5=1.5$
$h(3)=(f+g)(3)=f(3)+g(3)=2+0=2$
Plot the points corresponding to $h(x)$ and join them with lines:
