Chapter 2: Q. 60 (page 210)

For each of the equations in Exercises 59–62, y is defined as an implicit function of x. Solve for y, and use what you find to sketch a graph of the equation.
${(x - 1)}^{2} + {(y + 2)}^{2} = 4$

Short Answer

Expert verified

The equation for $y$ is $y = - 2 \pm \sqrt{4 - {(x - 1)}^{2}}$

Step by step solution

Step 1. Given Information

The given equation is ${(x - 1)}^{2} + {(y + 2)}^{2} = 4$

Step 2. Solve for y

${(x - 1)}^{2} + {(y + 2)}^{2} = 4 {(y + 2)}^{2} = 4 - {(x - 1)}^{2} y + 2 = \pm \sqrt{4 - {(x - 1)}^{2}} y = - 2 \pm \sqrt{4 - {(x - 1)}^{2}}$

Step 3. Graph of the Equation

We obtained $y = - 2 \pm \sqrt{4 - {(x - 1)}^{2}}$

The graph is of circle shown in the figure
