MAT 140 Test 2 Review

The material covers a range of mathematical concepts crucial for understanding and applying exponential and linear functions. Students are expected to construct models based on initial values and rates of change, identify whether data represents exponential growth or decay, and differentiate between linear and exponential relationships.
