Answer:
i. A bar graph is an appropriate display.
ii. A bar graph is appropriate because the frequencies are given.
Step-by-step explanation:
A bar graph is a graphical method that can be used to present an information from a sample of data. It requires drawing of bars of equal width and distance with respect to the information given.
While a pie chart is a method that requires presenting information in a circular chart with respect to each data in sectors of different central angles.
For the given question, the most appropriate method to use is the bar graph with respect to the given information. Thus, the statements that are correct about the data in the table are:
i. A bar graph is an appropriate display.
ii. A bar graph is appropriate because the frequencies are given.
If the function is vertically stretched by 4, the resulting function will be g(x) = 4(2)^x
<h3>Vertical stretch of a function</h3>
Exponential function is written in standard form as y= ab^x
where
a is the base
x is the exponent
Given the following exponential function f(x) = 2^x. If the function is vertically stretched by 4, the resulting function will be g(x) = 4(2)^x
