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.
An electronics store sells new and used Z-phones. The store manager made the
If these data are modeled by the line y=-10x+410, which best describes a valid prediction the manager could make, based on the data
A.If the store sells a Z-phone that is 30 months old, it will probably sell for only $50
B.If the store sells a brand-new Z-phone, it can expect a customer to pay about $410
C.For every one-month increase in phone age, the price a customer will pay increases by about $10
D.For every one-year increase in phone age, the price a customer will pay decreases by about $10
