Find g(4f(2)) where f(x)=1/2+x and g(x)=x(x+1)^3

 f(x)=1/x+x
 f(2)=1/2+2=2 1/2=5/2
4f(2)=4*5/2=2*2=10
g(x)=x(x+1)^2
g(4f(2))=g(10)=10(10+1)^2=10*11^2=1210
d) 1210

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 *_*

That is correct 8.25 multiplied by 7 is 57.75
