Chapter 4.4, Problem 5STP

The profit $y$ on the number $x$ of items a store sells is represented by the rule $y=2x-1$.

What does a table of values for the function rule and the graph of the function look like?

To determine

To find: The table of values and the graph.

Explanation of Solution

Give information: We are given with $y=2x-1$

Calculation:

Let’s find table of values by taking some random values for x.

Table:

x	$Y=2x-1$
-1	2(-1) -1 =-3
0	2(0) -1 =-1
1	2(1) -1 = 1
2	2(2)-1= 3

Now, let’s graph by representing the points on xy plane.

Graph:

  

Interpretation: The graph is a linear graph.
