Question

could someone help me?how to solve it.
gived function R(x) = X² + 2hx + h², so R(x+h) - R(x) / h = ....

Answer 1

do you mean [ R(x+h) - R(x)] / h OR R(x+h) -[ R(x) / h] ??? ;)

Answer 2

Sorry I don't mean like that. it's like I write before.

Answer 3

：D okaY if its [ R(x+h) - R(x)] / h
then R(x)
= X² + 2hx + h²=(x+h)²[R(x+h) - R(x) ]/ h
=[(x+h+h)² - (x+h)²]/h
=(x+2h+x+h)(x+2h-x-h)/h
=2x+3h

Answer 4

hope this helps:)
