Uploaded by Bintang

Function tables worksheet sheet 4A focuses on evaluating function machines. Learners compute f(x) for given inputs using eight linear rules, including f(x)=x-4, f(x)=6x, f(x)=½x, f(x)=x÷3, f(x)=2x+1, f(x)=20-x, f(x)=3x+5, and f(x)=¼x. The provided answers list matching input values and the corresponding outputs for each function table, supporting checking and practice.
