Answer to Initial Practice
Unit 3: Determining Whether the Slope of a Curve is Positive, Negative, or Zero

For each point on the curves below, identify whether the slope is positive, negative, or zero. Also, identify which are the maximum and minimum points (if any).

In graph (a):

  • Positive slope at points C and D
  • Negative slope at point A
  • Slope of zero at point B
  • Minimum point is B

In graph (b):

  • Positive slope at points A and E
  • Negative slope at point C
  • Slope of zero at points B and D
  • Maximum point is B
  • Minimum point is D
