SOLUTION: is this correct? f(x+1) for sqrt x^2+x =sqrt (x+1)^2+X+1 =sqrt x^2+2x+1+x+1 =sqrt x^2+3x+2 =2sqrt3x+1 thanks!!

You can put this solution on YOUR website!

f(x+1) for sqrt+%28x%5E2%2Bx%29
=sqrt%28+%28x%2B1%29%5E2%2BX%2B1%29
=sqrt%28+x%5E2%2B2x%2B1%2Bx%2B1%29
=sqrt+%28x%5E2%2B3x%2B2%29
You were correct up to here:
=2%2Asqrt%283x%2B1%29
the 2 does not come out of the square root, so your answer should have stayed =sqrt%28+x%5E2%2B3x%2B2%29
