Section 2.9 in Stewart's Calculus.

Preclass Learning Objectives:

• Lines are functions, even tangent lines.
  
• Linearization of a function f(x) approximates the values of f(x).
  
• The change along the y-axis can be approximated with linearization.

Section 3.1 in Stewart's Calculus.

Preclass Learning Objectives:

• Graphical understanding of extrema.
  
• Fermat's Theorem.
  
• Local extrema are critical points, the opposite isn't necessarily true.
  
• Extreme Value Theorem.
  
• The Closed Interval Method.

Section 3.3 in Stewart's Calculus.

Preclass Learning Objectives:

• If the derivative is positive on an interval, the original function is increasing on that interval. If the derivative is negative on an interval, the original function is decreasing on that interval.
  
• Concavity describes the direction a function is bending. A function is concave up on an interval, then the second derivative is positive on that interval and the function bends upwards. A function is concave down on an interval, the second derivative is negative on that interval and the function bends downwards.

Section 3.4 in Stewart's Calculus.

Preclass Learning Objectives:

• The end behavior of a function is described with limits.
  
• Horizontal asymptotes of power functions are either zero or do not exist (tend towards infinity).
  
• Determinate and indeterminate forms.
