Step 1. Given information.

We have:

$\sqrt{x + 1} = 4$

Step 2. Solve the equation algebraically.

The equation is $\sqrt{x + 1} = 4$ .

Square on both sides:

${(\sqrt{x + 1})}^{2} = {(4)}^{2} x + 1 = 16 x = 16 - 1 x = 15$

Step 3. Verify the solution using a graphing utility.

The solution of the equation is $x = 15$ .

Draw the graph of the equation $\sqrt{x + 1} = 4$ using the graphing utility:
