HELP PLEASE !!! Find and simplify the difference quotient f(x+h)−f(x) / h for the given function. f(x)=1/5x

Question

tkhunny · Answer

First, let's fix your notation.

You do not mean what you have typed: f(x+h)−f(x) / h
You mean this: [f(x+h)−f(x)] / h

Rememeber your Order of Operations and that typing "in-line" is a little different from text book printing.

Second, you'll have to specify a function.  There is no general procedure for all functions.

i forgot 1 thing :( sorry

anonymous · Answer

f(x)=1/5x

tkhunny · Answer

Okay.  What does f(x+h) mean, knowing f(x) = 1/5x?

By the way, do you mean $$\frac{ 1 }{ 5x }$$ or $$\frac{ 1 }{ 5 } \cdot x$$
?
You wrote the second one.
