#### Solutions

Chapter B, Problem 10E
To determine

## To calculate: To sketch the graph of the equation

Expert Solution

The graph of equation is sketched

### Explanation of Solution

Given information: Equation is |y|=1

Calculation:

Equation is given as follows:

|y|=1

Thus,

y=±1

Finding the points that lie on equation:

Case 1: Consider y=1

When x=0

y=1

When x=1

y=1

When x=2

y=1

Thus, (0,1),(1,1),(2,1) are the solution of equation and must lie on the equation.

Case 2: When y=1

When x=0

y=1

When x=1

y=1

When x=2

y=1

Thus, (0,1),(1,1),(2,1) are the solution of equation and must lie on the equation.

Plotting the points on graph,

y-axis

x-axis

Conclusion:

Hence, graph of equation is sketched
