Given that P=x:x is a factor of 6 is the domain of g(x)=x2+3x5, find the range of x.

A.

{-1, 5, 13}

B.

{5, 13, 49}

C.

{1, 2, 3, 6}

D.

{-1, 5, 13, 49}

Correct answer is D

P=x:x is a factor of 6P=1,2,3,6

g(x)=x2+3x5

g(1)=12+3(1)5=1+35=1

g(2)=22+3(2)5=4+65=5

g(3)=32+3(3)5=9+95=13

g(6)=62+3(6)5=36+185=49
