The page layout of a new mathematics book is being designed. Each page is to have a top and bottom margin of 3cm and left and right margins of 2cm. If the printed area inside the margins must be 200 cm2 find the expression for the area of the entire page (including the area of the margins) in terms of the full width of the page. What is the domain of this function? What sort of function is it (quadratic, cubic or...?). HINT: for the last part of this question you may need to put two terms over a common denominator.
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.
