Question 15

critical point definition

Answer 15

critical point = a point (c) in the domain of f at which

f’(c) = 0, or

f’(c) is undefined

Question 16

significance of the sign of f’(x)

Answer 16

if f’(x) > 0 (positive), the function is increasing on the given interval

if f’(x) < 0 (negative), the function is decreasing on the given interval

Question 17

inflection point (definition)

Answer 17

inflection point = a point on the graph where it changes from concave up to concave down

Question 18

relationship btwn inflection points and critical points

Answer 18

all inflection points are critical points, but not all critical points are inflection points

Question 19

significance of the sign of f’‘(x)

Answer 19

if f’‘(x) > 0 (positive), the function is concave up on the given interval

if f’‘(x) < 0 (negative), the function is concave down on the given interval
