Function Rules, Tables, and Graphs ALGEBRA 1 LESSON 5-3 51.[2] The graphs of all equations go through the point (0, 3). y = x + 3 and y = x2 + 3 share points on the right side of the y-axis. Both sides of the graphs y = x2 + 3 and y = |x|+ 3 go upward, but y = |x| + 3 has straight lines and y = x2 + 3 has curved lines. [1] at least two of the graphs drawn correctly 52.[4] a. Tables may vary. Sample: b. [3] appropriate methods but one calculation error [2] correct table but an error in graph [1] table with no graph OR graph with no table 5-3
