Use the DEFINITION of derivative to find f2 if fx x32x ie y
Use the DEFINITION of derivative to find f\'(-2), if f(x) = x^3-2x, i.e. you have to find limit of the provided function at the point. (show steps)
Solution
if a function is derivable at a point the function should be continuous
lt(x- -2+) = lt (x- -2-)
which is true
f\'(x) = 3 x^2 -2
f\'(-2)=10
