Lesson: Direct and Inverse Variation Mathematics

Students will be able to

• identify whether two variables, where one or both are powers or roots, vary directly or inversely with each other by considering a relation between them,
• write a relation between two variables given that powers or roots of the variables vary directly or inversely,
• find the value of a variable given the value of another variable taken to a power or root that varies directly or inversely with it,
• solve real-world problems involving powers and roots of two variables in direct or inverse variation.
