question
determine the value of y, if x is 4.

( y = sqrt{x} - 1 )

answer
y =

Explanation:

Step1: Substitute x = 4 into the equation

We have the equation \( y = \sqrt{x} - 1 \). Substitute \( x = 4 \) into it, so we get \( y = \sqrt{4} - 1 \).

Step2: Calculate the square root and simplify

First, calculate \( \sqrt{4} \), which is 2. Then subtract 1 from 2: \( 2 - 1 = 1 \).
