If f(x)=-2/x^2, and h is not equal to zero, then the difference quotient (f(x+h)-f(x))/h =? I'm not sure what to do for f(x+h)?

Question

what does the notation f(x) mean?

amistre64 · Answer

this is where confusion comes in, when we try to use "x" as part of the indepent variable, even tho it is perfectly fine to do so

amistre64 · Answer

if f(x) = -2/x^2 ; then determine f(a+h) - f(a)/h:  this format is easier to tell that x can be: a or (a+h)
