43210 In addition to level 3.0 and beyond what was taught in class, the student may:  Make connection with other concepts in math.  Make connection with other content areas. The student will understand and explain the difference between functions and non-functions using graphs, equations, and tables.  Compare properties of a function to a non- function. The student will be able to model and evaluate functions and non-functions.  Use graphs, equations, and tables to determine functions and non- functions. With help from the teacher, the student has partial success with level 2 and 3 elements. Even with help, students have no success with the functions. Focus 6 - Learning Goal #1: Students will understand and explain the difference between functions and non-functions using graphs, equations, and tables.

XY Complete the table to find the y- values and ordered pairs. y = 4 + 2x Substitute each x-value into the equation to solve for y. 1. y = 4 + 2(-1) y = y = 4 + 2(0) y = 4 y = 4 + 2(1) y = 6 6 y = 4 + 2(2) y = 8
