Question

Hello please help with this.

Answer 1

Answer:

Second option.

Step-by-step explanation:

First option is wrong since the $-f(x)$part has only one of the signs changed.

Second option is correct, even if expanding the square is a questionable choice, but the first bracket is indeed $(x+h)^2$

Third option distributed the 4 insides the square without taking it's square root first $(2x+2h)^2$would have been corrected.

Fourth option evaluated only the first term at $(x+h)$, but not the linear term.
