If f(x) = 2x and g(x)=1/x, what is the domain of (f o g)(x)?

x_> 0
all real numbers except x = 0
x< _0
all real numbers

(X)=2X-ALL real numbers except x=0x<_0

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
