About

This quiz covers functions and their properties, arithmetic sequences, and linear relationships, making it appropriate for 8th grade mathematics. Students need a solid understanding of domain and range concepts, recognizing that domain represents all possible input values (x-coordinates) while range represents all possible output values (y-coordinates). They must master function identification using the vertical line test and understand that functions have exactly one output for each input. For arithmetic sequences, students need to identify common differences, write both explicit formulas (an = a₁ + (n-1)d) and recursive formulas, and calculate specific terms. The linear relationships portion requires students to interpret tables and scatter plots, write equations in slope-intercept form, understand correlation types (positive, negative, no relationship), and work with linear regression equations to make predictions. Created by Ariel Sorrells, a Mathematics teacher in US who teaches grade 8. This comprehensive assessment serves multiple instructional purposes, from unit review to summative evaluation of student understanding across three interconnected algebraic concepts. Teachers can use this quiz as a culminating assessment after teaching functions, sequences, and linear relationships, or break it into smaller sections for formative assessment throughout the unit. The variety of question types - from basic identification to application problems involving real-world contexts like fundraising and travel - makes it excellent for differentiated instruction and homework assignments. This quiz aligns with Common Core standards 8.F.A.1 (understanding functions), 8.F.B.4 (linear functions), and 8.F.B.5 (analyzing functional relationships), providing teachers with valuable data on student mastery of these fundamental algebraic concepts that serve as building blocks for high school mathematics.
