If f(x)=x^2+1 and g(x)=1/x, find [f o g](x)

I need a little help in getting started. Please and Thank you.

I will be happy to critique your work. Follow the examples in the link.

To find [f o g](x), which represents the composition of two functions f and g, we need to substitute g(x) into f(x). In this case, we have f(x) = x^2 + 1 and g(x) = 1/x.

So, [f o g](x) can be found by substituting g(x) into f(x) as follows:

[f o g](x) = f(g(x)) = f(1/x)

To find f(1/x), we substitute 1/x into f(x) and evaluate the expression.

f(1/x) = (1/x)^2 + 1 = 1/x^2 + 1

Therefore, [f o g](x) = f(1/x) = 1/x^2 + 1

In conclusion, [f o g](x) = 1/x^2 + 1.
