1. For g(x) = x^2+2x+3, find and simplify:
2. If f(x)=x^2+1, find and simplify:
I'm not super concerned about what the answers are, but more on how to get to them. I know it looks like a case of just inputing whatever it is, but for some reason I come at it with an incomplete understanding of how to get to the solution of the problem.
Take for instance A in the first question.
g(x)=x^2+2x+3 when g(2+h)
I'm probably doing something very wrong because I do not seem to know how the answer is h^2+6h+11. I've got this so far:
