Criterion C (i, ii, iii, iv, v)
Criterion D (i, ii, iii, iv, v)
CCSS.8.FA.I Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output. CCSS.8.FA.2 Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change CCSS.8.FA.3 Interpret the equation y=mx+b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A-s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1.1), (2,4) and (3,9), which are not on a straight line. CCSS.8.EEB.5 Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects have greater speed
