Understanding Function Rules from Input-Output Tables | Math Tutorial #3305083 (License: Personal Use)

The image displays a function table listing x-values (0-4) and corresponding f(x) values (3, 5, 7, 9, 11), alongside a function rule stating “multiply by 2 and add 3.” Each row confirms the rule: for instance, 2 × 2 + 3 = 7. This reinforces linear function concepts in early algebra education.

Used in middle or high school math lessons, online tutorials, or Khan Academy-style content to teach students how to identify patterns and write algebraic expressions from data tables. Matches user intent to understand functional relationships visually.
