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.

Question

just need work shown. :)

a. Compute u = E(X), and interpret the result. [HINT: See Example 3.]
ANSWER !
6.5; there were, on average, 6.5 checkout lanes in each supermarket that was
surveyed.
b. Which is larger: P(X < µ) or P(X > µ)? Interpret the result.
ANSWER !
P(X < µ) = .42; P(X > µ) = .58 and is thus larger. Most supermarkets have
more than the average number of checkout lanes.
