Given that f(x)=x2+3x+6 and g(x)=x-3/2, solve for f(g(x)) when x=1

They want you to find the composite function and they evaluate it at a give value for x...first the composite function...

f(g(x))=(x-1.5)^2+3(x-1.5)+6

f(g(x))=x^2-3x+2.25+3x-4.5+6

f(g(x))=x^2+3.75, this is the completed composition function...now:

f(g(1)=1+3.75=4.75
