When
Inverse variation: x = 2 when y = 12.
Inverse variation: x = 25 when y = 2.
Inverse variation: x = 12 when y = 4.
Review Lesson 7.1: Without graphing, determine and indicate whether each function on the right represents exponential growth or exponential decay. Also, determine and indicate the y-intercept of each function on the right.
