Chapter 11: Q. 9 (page 772)

In Problems 5–24, graph each equation of the system. Then solve the system to find the points of intersection.
$y = \sqrt{x}; y = 2 - x$

Short Answer

Expert verified

The graph of the system of equations $y = \sqrt{x}; y = 2 - x$ is:

Step by step solution

Step 1. Given

The system of non-linear equation:

$y = \sqrt{x}; y = 2 - x$

To graph the equation and to find the point of intersection.

Step 2. Graph the equations

Graph the equations in the same plane.

Step 3. To find the point of intersection.

Equate both the equations,

$\sqrt{x} = 2 - x$

Squaring on both sides, we get,

$x = {(2 - x)}^{2} x = 4 - 4 x + x^{2} x^{2} - 5 x + 4 = 0$

Step 4. Solve the equation

$x^{2} - 5 x + 4 = 0 x^{2} - 4 x - x + 4 = 0 (x - 1) (x - 4) = 0 x = 1, 4$

Step 5. Find y

When $x = 1$ ,

$y = 2 - x y = 2 - 1 = 1$

When $x = 4$ ,

$y = 2 - (4) = - 2$

The points of intersection are $(1, 1), (4, - 2)$

Step 6. Plot the point of intersection

The graph of the system of non-linear equations with the point of intersection is:
