Question

f(x)=x^4
f(x+h)-f(x)/h, f(x)-f(a)/x-a

Answer 1

difference quotient problem?

Answer 2

Difference Quotient:
\[\frac{ f(x+h) - f(x) }{ h}\]

Answer 3

yes

Answer 4

So \(f(x)=x^4\)

Answer 5

do u know how to start?

Answer 6

yea I do but I don't get the answer that i'm suppose to

Answer 7

Oh okay, i see.
Do you mind showing me your work? Or do u want me to give u an example similar your question?

Answer 8

an example would be great I think im just doing something wrong

Answer 9

Difference Quotient:
\[\frac{ f(x+h) - f(x) }{ h }\]
\[f(x) = x^2 + 2\]
\[\frac{ (x+h)^2 + 2 - (x^2 + 2)}{ h }\]
\[\frac{ x^2 + 2xh + h^2 + 2 - x^2 - 2 }{ h}\]
\[\frac{ h(2x + h) }{ h }\]
\[2x + h\]

Please ask any questions you have with respect to the example.
