• Trace the graph of a function given a template.
• Identify the zeros of a function on a coordinate plane.
• Match the polynomial function with its corresponding graph.
• Match the graph of the polynomial function with its roots (zeros).

• Understand the following concepts and vocabulary: root, factor, quadratic, integer, real number, quadratic equation, quadratic formula, polynomial, degree, exponent, end behavior, square root, solution, terms, coefficient, intercept, intersect, zero.
• Understand that a root is where a function crosses the x-axis.
  
  
• Understand that the degree (largest exponent) of a polynomial determines the type and shape of the graph.
  
  
• Determine the direction (end behavior) of the sketch of the graph.
