If f(x)=5x+6 and g(y)=2y^2+ 8y-5 then g(f(x))	Choose the correct choice from the following choices
A) 52x^2+36x+85 B) 50x^2+160x+115 C) 85x^2+85x+85 D) 68x^2+87x+69 E) 87x^2+85x+58
g(f(x))=2(5x+6)^2+8(5x+6)-5 =2(25x^2+60x+36)+40x+48-5 = 50x^2+120x+72+40x+43   =50x^2+160x+115   Answer is 50x^2+160x+115
