Explain how to represent functions as graphs. give an example.

In order to represent functions as graphs, first we need to make a table of x and y values and plot those x,y values on the graph

Step-by-step explanation:

Suppose we have a statement as below:-

The cost of carrot is $2.50/lb

We can convert this statement into a function as

total cost = price per lb * weight of carrot bought

Let y be the total cost and x be weight of carrot bought

So,

y = 2.50 * x

where x is the independent variable and y is the dependent variable

A function represents an equation that shows the relationship between the input x and the output y.

The input x is also known as the Domain

The output y is also known as the Range

1) We can represent this function as a graph. In order to make a graph we need to begin by making a table containing inputs and their corresponding outputs.

Input, x (lb) Output, y ($)

0                       0

1                       2.50

2                       5.00

3                       7.50

The above table is generated by plugging in the values of x as 0, 1, 2, 3 into the function y=2.50*x and calculating the corresponding value of y

2) Now, we just need to plot the above pair of x,y values on the graph as shown in the attached figure.

answer: 32.68

x=2
