Describe how you would estimate the square root of a number that is not a perfect square

When you use a radical then if it gives a decimal then you just round it however it said like to the nearest whole or however it says to do it

Step-by-step explanation:

Step-by-step explanation:   this is how you would estimate the square root of a number if it is not a perfect square, here are 3 steps to help.

1. pick an estimate of the square root. example, if we find sqrt  of 5, if we pick 2.

2. divide  the number by the estimate. example,  5/2 = 2.5  

3 .  average the result  and the estimate

and this is how you would estimate the square root of a number that is not a perfect square, i hope this is useful.  or this

approximate between two whole numbers by finding the perfect squares nearest to the target number. indentify which value the non perfect square root is closet to, then use the irative process.

both of the explanations i have stated are correct so either one of them will work.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
