Question

Please help!

given f(x)=x^2+5
find f(x+h)-f(x)/h

Answer 1

\(f(x+h)=?\)

Answer 2

(Plug in "x+h" instead of "x" into the function, and simplify)

Answer 3

Let's be more careful with notation.

You have written: \(f(x+h) - \dfrac{f(x)}{h}\)

You probably meant [f(x_h) - f(x)]/h = \(\dfrac{f(x+h) - f(x)}{h}\)

Answer 4

tkhunny yes i meant that

Answer 5

You have to write it if you mean it. :-)
