If f(x) =

Answer 3

\[\frac{ x^2 }{ x+3 }\]

Answer 4

find f(x + h).

Answer 5

hey

Answer 6

Hi!

Answer 7

dont you plug in x+h for everywhere you see x?

Answer 8

we have to replace x with x+h, so we get:
\[\Large f\left( {x + h} \right) = \frac{{{{\left( {x + h} \right)}^2}}}{{\left( {x + h + 3} \right)}} = ...?\]

Answer 9

\[\frac{ x^2+h^2 }{ x+3+h}\]

Answer 10

hint:
\[\Large{\left( {x + h} \right)^2} = {x^2} + {h^2} + 2xh\]

Answer 11

\[\frac{ x^2+h^2+2hx }{ x+3+h}\]

Answer 12

that's right!

Answer 13

cool
