Is It a Function? | Function Machine + Vertical Line Test | Grades 7–8

Abella, Silver, and Finn run a ZillyPlanet math mission on functions. Learn the rule “one input, one output,” test graphs with the vertical line test, and catch the table trap where one x maps to two y-values. Pop quiz at the end: is y = 2x + 1 a function? Comment your answer before the reveal. #ZillyPlanet #Functions #Algebra #VerticalLineTest #MathClass #MiddleSchoolMath #HighSchoolPrep #STEMKids #EdTech #TeacherResources #Homeschool
