Let
f(x)=(x^2+3x-4)
and
g(x)=(x+4)
1. Find f*g and state the domain
2. Find f/g and state the domain

Measures of the angle of r, 31 s (x+4) t (3x+9)

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
