A function is a rule that pairs each input with exactly one output. There are 20 worksheets for 8th grade, 18 of them with answer keys, on telling functions from relations, linear and nonlinear functions, comparing functions and reading qualitative graphs, plus two reference sheets. What Makes a Relation a Function, Linear or Nonlinear From Equations and Match Stories to Qualitative Graphs are three of the sheets. Native sheets here practice 8.F.A.1, 8.F.A.2, 8.F.A.3, 8.F.B.4 and 8.F.B.5.

Frequently Asked Questions

A relation is a function when each input is paired with exactly one output. If any input appears with two different outputs, it is not a function. The sheets test this with sets of ordered pairs, tables, mapping diagrams and graphs.
