Question
3. (Applies to Standard D1)
This question will be referring to this definition
of the derivative of a function f at a point a.
S(a + h) – f(a)
f'(a) = lim
The figure shows the graph of a function y =
S(r) and a number a marked on the x-axis.
(a) Illustrate and label eaclh of the following quantities that appear iu this definition on the
graph. (You may assume h > 0.) Then write a short statement explaining in terms of the
figure what each quantity means.
i. f(a)
ii. h
iii. f(a + h)
iv. la+h)-f(a)
f(a + h) – f(a)
(b) Explain in terms of taugent and secant lines what the equation f'(a) = lim:
means. Include an explanation of what the symbol lim means and why it is needed.
