## anonymous one year ago I NEED HELP PLEASE f(x)=5x-x^2, f(5+h)-f(5) all over (h) h cannot = 0 go over step by step so i know how to do this

2. Nnesha

first find f(5+h) f(5+h) means x = 5+h so substitute x for 5+h into f(x) function

3. Nnesha

$\huge\rm f(\color{ReD}{x})=5\color{ReD}{x}-\color{ReD}{x}^2$ to find f(5+h) x with 5+h $\huge\rm f(\color{ReD}{5+h})=5(\color{ReD}{5+h})-(\color{ReD}{5+h})^2$ distribute and then combine like terms to find f(5) replace x with 5
