Answer:
Step-by-step explanation:
The three does nothing. When the equation is y = 3(x - 2)(x - 2) then the graph is stretched. See below for the imported graph.
To make this graph = 0 you make (x - 2) = 0
x - 2 = 0 Add 2 to both sides
x - 2 + 2 = 0 + 2 Simplify
x = 2
As you can see from the graph, the lowest point is 2,0. It just touches the x axis. That happens because there are 2 roots, both the same.
Graph
Red: (x - 2)(x - 2)
Blue:3(x - 2)(x- 2)

Answer: b. histogram
Step-by-step explanation:
A histogram is a graphical summary of data previously summarized in a frequency distribution. It is an accurate representation of the distribution of numerical data, the height of each bar shows how many fall into each range(the frequency of each range). Data from a frequency distribution table can be easily summarised graphically on a histogram.
