For each case, determine the two variables and tell whether the relationship is positive or negative. a. The more time is spent in studying his lessons, the higher is the average grade of Nelson. b. If the population of fox in a forest increases, the number of deer decreases. c. The more students enrolled in a school, the more teachers are needed. d. As a person ages, his memory decreases. e. The more workers are hired to paint the whole school, the sooner the job is done.
Transformation of Graphs
The word ‘transformation’ means modification. Transformation of the graph of a function is a process by which we modify or change the original graph and make a new graph.
Exponential Functions
The exponential function is a type of mathematical function which is used in real-world contexts. It helps to find out the exponential decay model or exponential growth model, in mathematical models. In this topic, we will understand descriptive rules, concepts, structures, graphs, interpreter series, work formulas, and examples of functions involving exponents.
