If f = {(1,2),(2,-4)} and g = {(0,3), (1,-2)}, find the following?
a) f + g ; do they want me to do this: ( 1+0, 2+3), (2+0, -4 -2)
b)Domaing of f+g
c) f/g
d) domain of f/g
i dont get it
Hi!
What that is saying is,
$\displaystyle f(1)=2$ and $\displaystyle f(2)=-4$
and
$\displaystyle g(0)=3$ and $\displaystyle g(1)=-2$
And remember
$\displaystyle (f+g)(x)=f(x)+g(x)$
and $\displaystyle (\frac{f}{g})(x)=\frac{f(x)}{g(x)}$
See if you can figure it out from here.
