Standards of Learning (SOL)

 
 Essential Knowledge and Skills
 
  • Identify the domain, range, zeros, and intercepts of a function presented algebraically or graphically.
  • Use the x-intercepts from the graphical representation of a quadratic function to determine and confirm its factors. 
  • Investigate and analyze characteristics and multiple representations of functions with a graphing utility.

AFDA.1 The student will investigate and analyze linear, quadratic, exponential, and logarithmic function families and their characteristics. Key concepts include domain and range; intervals on which a function is increasing or decreasing; absolute maxima and minima; zeros; intercepts; values of a function for elements in its domain; connections between and among multiple representations of functions using verbal descriptions, tables, equations, and graphs; end behavior; and vertical and horizontal asymptotes. 

AII.7 The student will investigate and analyze linear, quadratic, absolute value, square root, cube root, rational, polynomial, exponential, and logarithmic function families algebraically and graphically. Key concepts include domain, range, and continuity; intervals in which a function is increasing or decreasing, extrema; zeros; intercepts; values of a function for elements in its domain; connections between and among multiple representations of functions using verbal descriptions, tables, equations, and graphs; end behavior; vertical and horizontal asymptotes; inverse of a function; and composition of functions, algebraically and graphically.
