Let f(x)=5/x and g(x) =2x^2+5x. What two numbers are not in the domain of F o G?

1 answer:

6 0

F(x)=5/x
g(x)=2(x^2)+5x
f(x) has a domain of all real numbers excluding zero
g(x) has a domain of all real numbers
fog(x)=5/(2(x^2)+5x)
fog(x)=5/(x(2x+5))
fog(x) has a domain that excludes both zero and -5/2
