Let f be a real value function and x Î Df
lim ( ) ( )
f x h f x
® h
+ -
when it exists is
A) The derivative of f at a
B) The derivative of f at h
C) The derivative of f at x
D) The derivative of f at x = h

  • math -

    Can't read your funky fonts, but since
    there are no a's involved, and
    there x's and h's,

    I'd say (C)
