Abar graph can be displayed in many ways. which of the following does not represent a bar graph? a. simple bar graph c. composite bar graph b. scatterplot graph d. histogram

Option 'b' is correct.

Step-by-step explanation:

Since we know that a bar graph can be displayed in many different ways:

1) Simple bar graph : It used bars to display comparison between the categories of data.

2) Composite bar graph : It is a special type of bar graph to display multiple data comprised in a single row or column.

3) Histogram : It is a special type of bar graphs to uses frequency of numerical data to show the comparison between the categories of data.

4) Scatter plot graph : It is a two dimensional data uses dots to represent the values for two different variables, i.e. one plotted along y-axis and the other plotted along x-axis.

So, it uses dots rather than using bars.

Hence, Scatterplot graph is not represent a bar graph.

Thus, Option 'b' is correct.

step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
