Question 9106: my problem is g(x)=sq. rt. of x -1. i have four numbers for x and they are 0,1,4,9. i dont know how to solve because of the square root. i can do these kinds of problems without square roots, but that is really throwing me off. so just explain what to do with that and i can finish it. thanks

You can put this solution on YOUR website!
if you have g(x) = sqrt%28x%29-1 or should the square root be around (x-1)? and all you need to do is put the x-values into the equation, then...

g(0) = sqrt%280%29-1
g(0) = 0-1
g(0) = -1

g(1) = sqrt%281%29-1
g(1) = 1-1
g(1) = 0

g(4) = sqrt%284%29-1
g(4) = 2-1
g(4) = 1

you do the last one.
