Question

in the problem f(x+h)-f(x2+1)/h why does the first part become x+h2?

Answer 1

really depends on what
\[f(x)\] is

Answer 2

We understand the f(x2+1)/h, but we were not sure why all of the sudden the first part becomes x+h2

Answer 3

it could be literally anything. it would help if h(x) was given

Answer 4

Ok, the original problem was f(x+h)-f(x)/h It then turned into f(x+h)-f(x2+1)/h Does that help any?

Answer 5

H(x) is not given only f(x)
