Practice problem
Find functions f(x)f(x)f(x) and g(x)g(x)g(x) such that f(g(x))=(x+2)2f(g(x))=(x+2)^2f(g(x))=(x+2)2.
f(x)=x+2f(x)=x+2f(x)=x+2
f(x)=(x+2)2f(x)=(x+2)^2f(x)=(x+2)2
f(x)=x2f(x)= x^2f(x)=x2
g(x)=x2g(x)=x^2g(x)=x2
g(x)=x+2g(x)= x+2g(x)=x+2
g(x)=(x+2)2g(x)=(x+2)^2g(x)=(x+2)2
Type a concept, like “slope” or “photosynthesis”.
