Question

f(x)=x^7 -3, then f(x+h)

Answer 1

just replace 'x' by 'x+h' and expand

Answer 2

put x = x+h

Answer 3

expand only if necessary, else leave your answer in the 7th exponent form

Answer 4

i dont understand the expanding part

Answer 5

don't expand.
that will complicate it
just replace x by x+h

Answer 6

I did, not the right answer

Answer 7

\(f(x+h)= (x+h)^7-3\)

if your tool is showing this to be wrong, then either the question is incorrect or the tool is misbehaving

Answer 8

f(x)=x^7 -3, then f(x+h)
f(x)=(x+h)^7-3

Answer 9

hope you got it right :)
