Chapter 9.3, Problem 1P

Solve each equation by graphing the related function. If the equation has no real-number solution, write no solution.

$x^2-16=0$

To determine

To find: The real solution of the given equation.

Answer to Problem 1P

The real solution of the given equation are $x=4$ and $x=-4$ .

Explanation of Solution

Given information: Solve given equation by graphing the related function. If the equation has no real-number solution, write no solution.

Calculation:

Equation $x^2-16=0$

Graph of function $f\left(x\right)=x^2-16$

Equation $x^2-16=0$ cross the $x-axis$ at $x=4$ and $x=-4$ . These are the solution of the given equation.
